Can hcl and naoh form a buffer
WebHCl and NaCl A buffer consists of either a weak acid and its conjugate base or a weak base and its conjugate acid. Of the given compounds, HCN is the only weak acid. The conjugate base of HCN is CN- which is present in the salt NaCN, so they will form a buffer in solution. HCN and NaCN WebMar 6, 2024 · So looking at your list, a. has strongish acid, strong base; b. strongish acid, weak base; c. weak acid, and a half equiv strong base; d. weak acid, and a half equiv strong base. Solutions c. and d. will form a buffer. Their pH will be given by the buffer equation: pH = pKa +log10( [A−] [H A]) For more of the same on buffers, see this link.

WebWhy would HCl and NaOH be a bad buffer? Buffering requires a shift in equilibrium of a weak (partially dissociated) acid or weak base. HCl is a strong acid and NaOH is a strong base - both dissociate completely in aqueous solution, they do not go into equilibrium. No equilibrium = no buffering. 1 1 Lawrence C. WebExample 11.8.1.
