Help me fill in The blanks to this table please

Answer 1

When 10⁻⁷ M < [H⁺], the solution is acid, whereas when 10⁻⁷ M > [H⁺], the solution is basic.

The pH scale is used to determine the acidity or alkalinity of a solution. It is related to the concentration of H⁺ through the following expression.

$pH = -log [H^{+} ]$

• When [H⁺] > 10⁻⁷ M, the solution is acid.
• When [H⁺] = 10⁻⁷ M, the solution is neutral.
• When [H⁺] < 10⁻⁷ M, the solution is basic.

When 10⁻⁷ M < [H⁺], the solution is acid, whereas when 10⁻⁷ M > [H⁺], the solution is basic.
