Answer:
The pH of the solution is 1.66
Explanation:
Step 1: Data given
Number of moles HCl = 0.022 moles
Molar mass of HCl = 36.46 g/mol
Step 2: Calculate molarity of HCl
Molarity HCl = moles HCl / volume
Molarity HCl = 0.022 moles / 1 L = 0.022 M
[HCl] = [H+] = 0.022 M
Step 3: Calculate pH
pH = -log [H+]
pH = -log(0.022)
pH = 1.66
The pH of the solution is 1.66
Answer: 1.66
Explanation:
First, we calculate for the molarity of HCl as follows:
Number of mole HCl = 0.022mol
Volume = 1L
Molarity = mole /Volume
Molarity = 0.022mol /1L = 0.022mol/L
The dissociation equation of HCl is given below
HCl <==> H^+ + Cl^-
Since 1mole of HCl dissociate to produce 1 mol of H^+, therefore, 0.022mol/L HCl will also produce 0.022mol/L of H^+
We can obtain the pH is a solution using:
pH = - Log [H^+]
pH = - Log 0.022
pH = 1.66
