Answer:
pH= 3.30
Step-by-step explanation:
Hydrochloric acid is a strong acid that completely dissociates in water.
For a 0.00050 M HCl solution the concentration of the hydrogen ions, [ H + ]
, is 0.00050 moles/liter (i.e. 0.025 M).
The pH is defined as − log [ H + ] .
Substituting 0.00050 into the equation for pH we find that the 0.00050 M HCl solution has a pH of -log(0.00050) = 3.30.
