2. Add excess sodium cyanide to a solution containing copper ions, causing the blue color of the solution to disappear, while releasing a highly toxic gas.

3. Boil copper(I) chloride in concentrated $\mathrm {NaOH}$ solution, where the copper element is completely converted into a red solid.

4. The hydrolysis disproportionation of $\mathrm{ I F } _ { 3 }$ yields three common inorganic substances.

5. Dissolve elemental $\mathrm {Pb}$ in sodium hydroxide and write the ionic equation for the reaction.

6. Treat $\mathrm { { M n } ( I O _ { 3 } ) _ { 2 } }$ with bromine trifluoride at $8 0 0$ $\mathrm { K }$ to prepare a fluoride, with another fluoride also formed in the products.

Write and balance the equations for the above processes, simplifying the coefficients to the smallest integer ratios. For chemical processes in aqueous solutions, use ionic equations. The following statements are correct:

2.向含有铜离子的溶液中加入过量氰化钠，溶液的蓝色消失，同时逸出一种剧毒气体。

3.氯化亚铜在浓$\mathrm {NaOH}$溶液中煮沸，其中的铜元素完全转化为一种红色固体。  

4.$\mathrm{ I F } _ { 3 }$ 水解歧化，产物为三种常见无机物。  

5.$\mathrm {Pb}$ 单质溶于氢氧化钠中，写出反应的离子方程式。
