Answer:
pH = 2,4
Explanation:
pH is defined as a measure of acidity or alkalinity of a solution based on H⁺ concentration
The HCl dissociates in water thus:
HCl → H⁺ + Cl⁻
That means that moles of HCl are the same than H⁺.
0,35gHCl = 9,6x10⁻³ moles HCl ≡ moles H⁺
H⁺ molarity is: = 3,84x10⁻³M
As pH = -log [H⁺]
<em>pH = 2,4</em>
