Answer:
1,Heating a mixture of concentrated sulfuric acid and common salt above 200°C can cause the following disadvantages:
Glass apparatus may crack
Fuel is wasted
Sodium sulfate forms a hard crust that sticks to the glass
When heated to decomposition, sulfuric acid emits toxic fumes of sulfur oxides.
Sulfuric acid is a highly corrosive, dense, oily, clear, colorless liquid. It's miscible in water in all proportions. When mixing, caution is required due to the tremendous evolution of heat that can cause violent reactions.
When working with sulfuric acid, you should wear the following personal protective equipment (PPE):
Chemical safety goggles
Face shield
Chemical protective clothing, such as gloves, aprons, and boots

2,When mixed, Chile saltpeter and sulfuric acid form a hard crust.
Sulfuric acid is a corrosive, reactive, and potentially explosive chemical. It can cause:
Skin burns, Eye burns, Difficulty breathing, Pulmonary edema, Headache, Nausea, Vomiting.
Sulfuric acid can also ignite organic materials.
Answer:
The mixture of concentrated sulphuric acid and sodium nitrate must not be heated above 200oC because of the following reasons: Nitric acid will decompose into nitric oxide gas. Potassium or sodium sulphate will be formed, which may stick to the glass walls and cannot be removed easily. Glass apparatus may also break.
