WebSep 1, 2024 · HCl (aq) → H + (aq) + Cl - (aq) A strong acid has a pKa value less than -2. The pKa value of the acid depends on the solvent. For example, hydrochloric acid has a pKa value of about -5.9 in water and -2.0 in DMSO, while hydrobromic acid has a pKa value around -8.8 in water and about -6.8 in DMSO. A Closer Look at Some of the Strong Acids Weba solution of 0.2M hydrochloric acid (HCl) a solution of 0.2M sodium hydroxide (NaOH) pH meter to measure pH of the solution. Experiment 1: The pH of solution A is 7.0 i.e. it’s neutral. When we add 10 mL of 0.2M HCl to it, the pH decreases to 1.5. On the other hand, when we add 10 mL of 0.2M NaOH to solution A the pH shoots up to 12.5. nofap statistics
