Answer:
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.
