$CuCl_2$

Vedclass · Answer

(B) $(1)$ $Na_2CO_3$ is a salt of a strong base $(NaOH)$ and a weak acid $(H_2CO_3)$, so it is basic $(pH > 7)$.$(2)$ $CuCl_2$ is a salt of a weak base $(Cu(OH)_2)$ and a strong acid $(HCl)$, so it is acidic $(pH $(3)$ $CH_3COONa$ is a salt of a strong base $(NaOH)$ and a weak acid $(CH_3COOH)$, so it is basic $(pH > 7)$.$(4)$ $NaNO_3$ is a salt of a strong base $(NaOH)$ and a strong acid $(HNO_3)$, so it is neutral $(pH = 7)$.Therefore, $CuCl_2$ has the least $pH$ value.

Which of the following aqueous salt solutions has the least $pH$ value?
