Question

Q.4 On diluting solution of pH of 4, its pH will
(a) Remain same
(c) Decrease
(b) Increase
(d) Undergo a chemical change.​

Answer 1

Answer:

b). decrease

the pH of a basic solution is greater than 7 as you dilute solution it become more and more like pure water show the pH move closer to the ph of pure water pH 7 the pH decrease on dilution

Answer 2

On diluting the solution of pH of 4, its pH will (b) Increase.

Explanation:

• Diluting the solution with a pH of 4 increases the pH value.
• On dilution, the concentration of ions decreases due to the increase in the volume of the solution.
• Thus, Diluting an acid by adding more water increases the pH of the solution to 7 to make it less acidic.
• Hence, the pH will increase.
• Thus, the correct answer among all the options is option (b) Increase.
