This week for tech we have been learning acids and bases. All liquids and bases are either bases or acid depending on the iron. People use a Ph scale to find out if it is acids or bases, or neutral. PH scales 0 - 14 0 - 7 are acids 7 - 14 are bases Strong acid Weak acid Boric acid can be in insects Plants have acids in the leaves Sodium HydroxideBaking soda Lactic acid
The things we used were Baking soda Distilled water Window cleaner Toilet bowl cleaner Lemon juice Milk Orange juiceApple juice. First of all, using the macker, label each item you will be testing
We measure about 4 or 5 drops of each item into the well plate and mark it for that item..
