Whats the ph of water

7

Explanation:

The pH of water is 7.

 pH is the convenient scale for expressing the level of acidity or alkalinity of aqueous solutions.

An acidic solution has a pH value less than 7.

As pH decreases, the acidity of solutions increases.

Neutral solutions have a pH of 7.

An alkaline solutions has a pH greater than 7 and the level of alkalinity increases as the pH increases.

  Water has a pH of 7 because the concentration of hydrogen and hydroxyl ion is equal.

it is stable as it is in group 0 which have full outer shells of electrons

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
