`5.` `HCl-` hydochlodric acid `-`  acid

`6.HNO_3-` nitric acid `-` acid

`7.H_2SO_4-` sulfuric acid `-` acid

`8.Fe(OH)_2-` iron (II) hydoxide `-` base

`9.Ca(OH)_2-` calcium hdroxide `-` base

`10.Cu(OH)_2-` copper(II)hydroxide `-` base

Đáp án+Giải thích các bước giải:

\begin{array}{|c|c|c|}\hline \text{HCl}&\text{hydrochloric acid}&\text{acid}\\\hline \text{HNO3}&\text{nitric acid}&\text{acid}\\\hline \text{H2SO4}&\text{sulfuric acid}&\text{acid}\\\hline \text{Fe(OH)2}&\text{iron(II) hydroxide}&\text{base}\\\hline \text{Ca(OH)2}&\text{calcium hdroxide}&\text{base}\\\hline\text{Cu(OH)2}&\text{copper(II) hydroxide}&\text{base}\\\hline\end{array}

`-` Acid thường có `H` liên kết với gốc acid.

`-` Base sẽ có đuôi `OH.`
