What is an elastic collison?

Encounter between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy.

The pH of the substance is 8.25. The solution is basic.

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydronium ion concentration. The acids have pH ranging from 1 to 6.9 , salts have pH of 7 and bases have pH ranging from 7.1 to 14.

 

Putting in the values:

Thus as pH is more than 7, the solution is basic.

The pH of the substance is 8.25. The solution is basic.
