Question

question 18 (1 point) what is the ph of a 0.0001 m aqueous solution of hcl? 1 2 3 4

Explanation:

Step1: Recall pH formula

pH = -log[H⁺]

Step2: Determine [H⁺] for HCl

HCl is a strong - acid and dissociates completely in water. For 0.0001 M HCl, [H⁺]=0.0001 M = 1×10⁻⁴ M.

Step3: Calculate pH

pH=-log(1×10⁻⁴) = 4

Answer:

4
