my child is doing a sci. fair project and she needs to change the level of water with acidic drops and basic drops. where can i buy this? help please asapHow to change ph level of water to 9 and 5?
Some common bases are bleach, ammonia, soap, baking soda, draino to get high pH. Some common acids are lemon juice, vinegar, and sulfuric sulfuric acid if you want to try and get a really low pH.
You can buy most of these substances at your local supermarket and you can inquire at your local chemists for the rest of them.
