Answer:
pH = 6.5
Explanation:
pH is the negative log of the hydronium concentration, [H⁺]. Since we are given the concentration, we can just plug it in the following equation:
pH = -log[H⁺] = -log[3.5 x 10^-7 M] = 6.5
The answer is A. You record ,write down, what is happening with the experiment.
For example phosphorus and oxygen can covalently bond to form a polyatomic ions, PO4³⁻ and PO3³⁻.
