Can hcl be used as a buffer
WebOct 20, 2024 · The first option has a strong acid (HCl) and hence the solution cannot form a buffer. The second option has a strong base (NaOH) which is not a conjugate base of HNO₂. Thus the solution cannot form a buffer. The third option has HNO₂ which is a weak acid and NaNO₂ which is it's salt, hence it can form a buffer. WebA buffer solution can resist a change in its pH with the addition of an acid or a base. Buffer solutions are usually made by mixing weak acids/bases with their salt solutions in an aqueous medium. The resulting buffer solutions will be respectively either acidic or basic. ... HCl (aq) → H + (aq) + Cl-(aq) 7. ...
