Explain how you would prepare a sulphuric acid solution.
To prepare a sulphuric acid solution, you would need the following materials: concentrated sulphuric acid (98-99%), distilled water, a glass container, protective goggles, gloves, and a stirring rod. Here's a step-by-step guide on how to prepare the solution:
1. Ensure you are in a well-ventilated area or under a fume hood and wear appropriate safety gear, including goggles and gloves, as concentrated sulphuric acid is highly corrosive.
2. Set up a glass container, preferably a beaker or a glass bottle, which is resistant to acid.
3. Measure the desired volume of sulphuric acid you want to prepare. Be cautious in handling the acid and avoid contact with your skin or eyes. Use a measuring cylinder to achieve accuracy.
4. Slowly and carefully pour the measured sulphuric acid into the glass container, avoiding any spillage. It's important to always add acid to water and not vice versa to prevent an exothermic reaction and splashing.
5. Fill the remaining volume of the glass container with distilled water. Ensure you use distilled water to prevent any impurities that may affect the accuracy of your solution.
6. Use a glass stirring rod to gently mix the solution. Make sure not to breathe in any fumes and keep the container away from your face. Stir until the acid and water are thoroughly mixed.
7. Allow the solution to cool down before transferring it into a storage container if needed. Remember to label the container properly with the concentration, date, and any other necessary information.
Always exercise caution while handling concentrated sulphuric acid as it poses various safety risks. If you're unsure or inexperienced, it's best to seek assistance from a trained professional.
