Answer:
True
Explanation:
as the ph of pure water is 7
(-)log(10^-7) = 7
The statement if the pH of pure water is 7.0, the hydroxide ion concentration in pure water is 1 × 10⁻⁷M is true.
How do we calculate the hydroxide ion concentration?
Hydroxide ion concentration in the solution will be calculated by using the below equation as:
pOH = -log[OH⁻]
Relation between pH and pOH is :
pH + pOH = 14
Given that, pH = 7
So, pOH = 14 - 7 = 7
By using first equation, we have
7 = -log[OH⁻]
[OH⁻] = 10⁻⁷M
Hence, hydroxide ion concentration in pure water is 1×10⁻⁷M.
