WebTo determine pH, you can use this pH to H⁺ formula: pH = -log ( [H⁺]) Step by Step Solution to find pH of 0.2 M : Given that, H+ = 0.2 M Substitute the value into the formula pH = -log ( … WebMay 8, 2015 · It's simple. We all know that density = Mass/volume. The density of your hcl is 1.179. Mass of hcl in one molar solution which is the molar mass is 36.5. but the percentage purity of the hcl is 35% according to you. That means, 35% of that 36.5g is in 1 molar/dm3. Which means, your mass will be 35% of 36.5 =36.5*35/100 35.5*0.35=12.775 WebJun 19, 2024 · Calculate the pH of a solution with 1.2345 × 10 − 4 M HCl, a strong acid. Solution The solution of a strong acid is completely ionized. That is, this equation goes to completion HCl ( aq) H ( aq) + Cl − ( aq) Thus, [ H +] = 1.2345 × 10 − 4. pH = − log ( 1.2345 × 10 − 4) = 3.90851 Exercise 7.14. 1 chinese red letters
