The pH of the solution in which 4.85g of HCl is present is 1.3.
How do we calculate pH?
pH of the solution will be calculated by using the below equation:
pH = -log[H⁺]
Relation between the mass and moles of any substance will be represented as:
- n = W/M, where
- W = given mass
- M = molar mass
Moles of HCl = 4.85g / 36.4g/mol = 0.13 moles
Given volume = 2.5 L
Concentration in terms of molarity will be calculated as:
M = n/V
M = 0.13mol / 2.5L = 0.05 M
So, 0.05M HCl solution have the same amount of concentration of H⁺ ion. Now pH will be calculated as:
pH = -log(0.05) = 1.3
Hence required pH of the solution is 1.3.
