Question

What are the factors that affect the value of the ionic products of water and how . Write in brief.

Answer 1

Answer:

product of concentrations of H+ and OH- ions in water at a particular temperature is known as ionic product of water. The value of Kw increases with the increase of temperature, i.e., the concentration of H+ and OH- ions increases with increase in temperature.

Temperature (°C) Value of Kw

0 0.11 x 10-14

10 0.31 x 10-14

25 1.00 x 10-14

100 7.50 x 10-14

The value of Kw at 25°C is 1 x 10-14. Since pure water is neutral in nature, H+ ion concentration must be equal to OH- ion concentration.

[H+] = [OH˜] = x

or [H+][OH-]=x2= 1 x 10-14

or x = 1 x 10-7 M

or [H+] = [OH-] = 1 × 10-7 mol litre-1

Answer 2

Answer:

The product of concentrations of H+ and OH- ions in water at a particular temperature is known as ionic product of water. The value of Kw increases with the increase of temperature, i.e., the concentration of H+ and OH- ions increases with increase in temperature. The value of Kw at 25°C is 1 x 10-14.
