Answer:
(a) Neutral.
(b) Basic.
(c) Basic.
Explanation:
Hello,
In this case, we must take a look of both the cation's and anion's nature, it means, if they come from a strong or weak acid or base, thus:
(a) Chromium (III) hydroxide is a strong base and nitric acid is a strong acid, consequently, chromium (III) nitrate is a neutral base since every ion is neutralized.
(b) Sodium hydroxide is a strong base and the hydrosulfuric acid is a weak acid, so there will be unreacted OH- ions, consequently, sodium hydrosulfide is a basic salt.
(c) Zinc hydroxide is a strong base and acetic acid is a weak acid, therefore, as in the previous salt, this is a basic salt.
Best regards.
