\(\begin{array}{l}
1)\\
NaOH + HCl \to NaCl + {H_2}O\\
{n_{NaOH}} = \dfrac{1}{{40}} = 0,025mol\\
{n_{HCl}} = \dfrac{1}{{36,5}} = 0,027mol\\
\dfrac{{0,025}}{1} < \dfrac{{0,027}}{1} \Rightarrow HCl\text{ dư}\\
\text{Dung dịch sau phản ứng tạo môi trường Axit}\\
2)\\
a)\\
NaCl + AgN{O_3} \to AgCl + NaN{O_3}\\
{n_{NaCl}} = 0,5 \times 2 = 1mol\\
{n_{AgN{O_3}}} = 0,6 \times 2 = 1,2mol\\
\dfrac{1}{1} < \dfrac{{1,2}}{1} \Rightarrow AgN{O_3}\text{ dư}\\
{n_{AgCl}} = {n_{NaCl}} = 1mol\\
{m_{AgCl}} = 1 \times 143,5 = 143,5g\\
b)\\
{n_{AgN{O_3}d}} = 1,2 - 1 = 0,2mol\\
{n_{NaN{O_3}}} = {n_{NaCl}} = 1mol\\
{C_{{M_{AgN{O_3}d}}}} = \dfrac{{0,2}}{{0,5 + 0,6}} = \dfrac{2}{{11}}M\\
{C_{{M_{NaN{O_3}}}}} = \dfrac{1}{{1,1}} = \dfrac{{10}}{{11}}M
