Question

pH of 600 mL of 0.1 M HCl solution will be

Answer 1

• According to the question ,we have to determine the PH of 600 mL of 0.1 M HCl solution .

•Solution:-

So total moles of HCl = 0.01 × 0.1 = 0.001 moles

according to the question the total volume is 600 ml

so,M = 0.001/0.6 = 0.00167 mol/Lit

we know

pH = - log (M)

so, pH= - log(0.001/0.6) = 2.77

So,PH of 600 mL of 0.1 M HCl solution will be 2.77.

Answer 2

pH of 600 mL of 0.1 M HCl solution will be  1

Explaination:

Data given

concentration of HCl = 0.1 M

Volume is 600ml

To know the hydrogen ion concentration in HCl solution, we know that concentration of H+ ions is equal to Cl-, ions so here the concentration of H+ ion is 0.1 m.

the pH of the solution of acid is calculated after knowing the hydrogen ion concentration in the solution.

formula used is:

pH = - log[H+]

putting the values in the above equation

pH = -log[0.1]

pH = 1

the value of pH shows that HCl is a strong acid and the solution of the HCl given in the question is highly acidic.
