Question

As the ph value of a neutral solution increases
A)basic property decreases and number of OH- ions increases.
B)acidic property increases and number number of H+ ions decreases.
C)basic property increases and number number of OH- ions increases.
D)acidic property decreases and number number of H+ ions increases.

Answer 1

Answer:

C)basic property increases and number number of OH⁻ ions increases.

Explanation:

When the pH value increases, it means that the solution is becoming more basic, as geater values of the pH indicates increase in pH value. For eg the neutral solution pH 7 increases to become a pH of 10 then here, the basic nature is increasing. The same applies for the case in the question.

We know that as basicity increases, OH⁻ ions increases.

Hence, basic property increases and number of OH⁻  ions increases as pH value increases.

Hope it's clear :)

Answer 2

Answer: c) Basic property increases and no. of OH⁻ ions increases.

Explanation: ph value for a neutral solution is 7. When the ph value increases:

• Basic property of that solution increases
• Acidic property of that solution decreases
• OH⁻ ions increase and H⁺ ions decreases

Therefore only option c can be correct which states that basic property increases and no. of OH⁻ ions increases. All other options are wrong.
