Question

what is the ph of a solution that is 0.001 M in HCl? ( show all work)

Answer 1

Hydrochloric acid is a strong acid, which means that it dissociates completely in aqueous solution to form bychomium ions Hot cmd chloride anions, cien 1:1 mole ratio. Every mole of hydrochloric acid will dissociates to produce one mole of hidronium ions and one mole of chloride anions in aqueous solution.

The balanced chemical equation is наlcaq + +9) - Hotag) + са ) The pH of solution is simply a measure of the concentration of hydronium ions . pH = -log(CH20]) one mole of Bedronium ions for every one mole of hydrochloric acid [Haot] - [HCI] = 0.001m.

This means that the pr of the solution will be pH = -log (0.001) pH = 3
