pH, Ka, pKa & Kw Calculations ( CIE A Level Chemistry )

Revision note.

Head of Science

Calculating pH, Ka, pKA & Kw

• The pH indicates the acidity or basicity of an acid or alkali
• Acids have pH between 0-7
• Pure water is neutral and has a pH of 7
• Bases and alkalis have pH between 7-14
• The pH can be calculated using: pH = -log 10 [H + ]
• The pH can also be used to calculate the concentration of H + ions in solution by rearranging the equation to:

[H + ] = 10 -pH

Worked Example: Calculating the pH of acids

pH = -log [H + ]

= -log 1.32 x 10 -3

K a & p K a

• It is the equilibrium constant for the dissociation of a weak acid at 298 K
• For the partial ionisation of a weak acid HA the equilibrium expression to find K a is as follows:

HA (aq) ⇌ H + (aq) + A - (aq)

• The concentration of hydrogen ions due to the ionisation of water is negligible
• The dissociation of the weak acid is so small that the concentration of HA is approximately the same as the concentration of A -
• The equilibrium position lies to the right
• The acid is almost completely ionised
• The acid is strongly acidic
• The equilibrium position lies to the left
• The acid is only slightly ionised (there are mainly HA and only a few H + and A - ions)
• The acid is weakly acidic
• Since K a values of many weak acids are very low , p K a values are used instead to compare the strengths of weak acids with each other

p K a = -log 10 K a

• The less positive the p K a value the more acidic the acid is

Worked Example: Calculating the K a & p K a of weak acids

• Step 1: Write down the equation for the partial dissociation of ethanoic acid

CH 3 COOH (aq) ⇌ H + (aq) + CH 3 COO - (aq)

• Step 2: Write down the equilibrium expression to find K a

• Step 3: Simplify the expression

The ratio of H + to CH 3 COO - is 1:1

The concentration of H + and CH 3 COO - is, therefore, the same

The equilibrium expression can be simplified to:

• Step 4: Substitute the values into the expression to find K a

= 1.74 x 10 -5

• Step 5: Determine the units of K a

= mol dm -3

The value of K a is therefore 1.74 x 10 -5 mol dm -3

• Step 6: Find p K a

p K a = - log 10 K a

= - log 10 (1.74 x 10 -5 )

• It is the equilibrium constant for the dissociation of water at 298 K
• Its value is 1.00 x 10 -14 mol 2 dm -6
• For the ionisation of water the equilibrium expression to find K w is as follows:

H 2 O (l) ⇌ H + (aq) + OH - (aq)

• As the extent of ionisation is very low, only small amounts of H + and  OH - ions are formed
• The concentration of H 2 O can therefore be regarded as constant and removed from the K w expression
• The equilibrium expression therefore becomes:
• As the [H + ] = [OH + ] in pure water, the equilibrium expression can be further simplified to:

K w = [H + ] 2

Worked Example: Calculating the concentration of H + of pure water

• Step 1: Write down the equation for the partial dissociation of water

  In pure water, the following equilibrium exists:

• Step 2: Write down the equilibrium expression to find K w

Since the concentration of H 2 O is constant, this expression can be simplified to:

K w = [H + ] [OH - ]

• Step 4: Further simplify the expression

The ratio of H + to OH - is 1:1

The concentration of H + and OH - is, therefore, the same and the equilibrium expression can be further simplified to:

• Step 5: Rearrange the equation to find [H + ]
• Step 6: Substitute the values into the expression to find K w

= 1.00 x 10 -7 mol dm -3

pH = -log 10 [H + ] TO [H + ] = 10 -pH

p K a = - log 10 K a TO K a = 10 -p Ka

Chem Article

Organic chemistry assignment-1 reagents and reaction mechanism, spectroscopy.

Organic chemistry can be a daunting subject, especially when preparing for competitive exams like CSIR NET, GATE, IIT JAM, UPSC, and others. Understanding the intricacies of reagents, reaction mechanisms, and spectroscopy is crucial for mastering this subject. To aid students in their preparation, ChemArticle has introduced a series of assignments designed to deepen your understanding and sharpen your problem-solving skills.

What to Expect in Assignment-1?

The first installment in this series, Assignment-1 , is meticulously crafted to cover essential topics within organic chemistry that are pivotal for competitive exams. The assignment focuses on three primary areas:

Reagents : The assignment begins with an exploration of various organic reagents, their properties, and their roles in chemical reactions. Understanding reagents is fundamental because they dictate the course and outcome of organic reactions. This section challenges students to identify reagents, predict their behavior in reactions, and understand their mechanisms of action.

Reaction Mechanisms : The heart of organic chemistry lies in understanding how reactions occur at the molecular level. This section of the assignment delves into different reaction mechanisms, emphasizing the step-by-step processes that lead to the formation of products. Mastering these mechanisms is key to predicting reaction outcomes and designing new synthetic routes.

Organic Spectroscopy: Finally, the assignment introduces students to the world of spectroscopy, a vital tool for identifying and characterizing organic compounds. Questions in this section will test your ability to interpret various spectroscopic data, such as NMR, IR, and UV-Vis spectra, to deduce the structure of organic molecules.

How to Utilize This Assignment

A new assignment will be published every two days on our official website. These assignments are designed not just for practice, but as a comprehensive learning tool that will challenge your understanding and push you to think critically. To get the most out of Assignment 1:

Practice Regularly: Make it a habit to solve the assignment when it is released. This will keep you in sync with the series and ensure steady progress.

Review and Analyze: After completing the assignment, spend time analyzing your answers. Understand why a particular reagent works the way it does, or why a specific reaction follows a certain mechanism.

Refer to Additional Resources: If you encounter difficulties with any of the concepts, don’t hesitate to refer to textbooks, research papers, or online resources to clarify your doubts.

Submit Your Assignment: Submission is an integral part of the learning process. By submitting your answers, you can review them, receive feedback, and identify areas needing improvement.

Assignment Volume-1

Organic Chemistry Assignment-1

First Edition, Volume-1, Issue-1 ; Topic covers Reagents and Reaction mechanism, spectroscopy questions and answers; Exam: CSIR NET/ GATE/ IIT JAM/ UPSC/ TIFR/ BARC; It's free for everyone.

ChemArticle’s Assignment-1 is more than just a set of questions; it’s a step towards mastering organic chemistry. Whether you’re preparing for a national-level exam or simply want to enhance your understanding of the subject, this assignment is an invaluable resource.

Download the PDF of Organic Chemistry Assignment-1 here and begin your journey to success. Stay tuned for more assignments and make sure to practice consistently!
