How will you obtain
1)sulphric acid from a sulphur trioxide
2)potassium hydroxide from potassium oxide
1) Sulphuric acid (H2SO4) can be obtained from sulphur trioxide (SO3) by adding water. When SO3 is added to water, it reacts vigorously to produce sulphuric acid. The balanced chemical equation for this reaction is:
SO3 + H2O → H2SO4
2) Potassium hydroxide (KOH) can be obtained from potassium oxide (K2O) by adding water as well. When K2O is added to water, it reacts to form potassium hydroxide. The balanced chemical equation for this reaction is:
K2O + H2O → 2KOH
To obtain sulphuric acid from sulphur trioxide, you can follow these steps:
1. Gather the necessary materials and equipment, including sulphur trioxide, water, and a suitable container.
2. Take caution and wear appropriate protective equipment, such as gloves and safety goggles, as sulphuric acid is a strong corrosive substance.
3. Carefully add the sulphur trioxide to the water, NOT the other way around. This is an exothermic reaction, so the mixture may heat up and release fumes. Stir the mixture slowly to avoid splashing.
4. Continue stirring until the sulphur trioxide is completely dissolved in water. This will result in the formation of sulphuric acid.
5. Allow the solution to cool down before handling or using it.
To obtain potassium hydroxide from potassium oxide, you can follow these steps:
1. Gather the necessary materials and equipment, including potassium oxide and water.
2. Take caution and wear appropriate protective equipment, such as gloves and safety goggles, as potassium hydroxide can be caustic and harmful.
3. Add the potassium oxide to water slowly, while stirring continuously. Do NOT add water to the potassium oxide, as it may cause a violent reaction.
4. The potassium oxide will react with water to form potassium hydroxide. This is an exothermic reaction, so the mixture may heat up.
5. Continue stirring until the potassium oxide is completely dissolved in water and the solution has cooled down.
6. Once the solution is ready, you can use it accordingly in your desired applications.
Remember to handle all chemicals with care and follow appropriate safety procedures when performing chemical reactions.
