Câu 1.

Dùng dung dịch axit clohidric \(HCl\) vào hai chất trên:

 +Thấy xuất hiện khí bay ra: kali cacbonat \(K_2CO_3\)

    \(K_2CO_3+2HCl\rightarrow2KCl+H_2O+CO_2\uparrow\)

 +Không hiện tượng: kali sunfat \(K_2SO_4\)

Câu 2.

 a)\(Na_2O+H_2O\rightarrow2NaOH\)

b)\(Na_2O+H_2O\rightarrow2NaOH\)

\(6NaOH+Fe_2\left(SO_4\right)_3\rightarrow2Fe\left(OH\right)_3+3Na_2SO_4\)

Câu 3.

 \(n_{NaOH}=\dfrac{20}{40}=0,5mol\)

 \(n_{HNO_3}=\dfrac{20}{63}\approx0,3mol\)

 \(NaOH+HNO_3\rightarrow NaNO_3+H_2O\)

   0,5          0,3 

 \(\Rightarrow NaOHdư\) \(\Rightarrow\)Qùy hóa xanh.
