1. Dissolve 6.5g KOH (potassium hydroxide) in 1600mL water and add several drops of universal indicator. Place in 2000mL graduated cylinder.
EFFINGHAM COUNTY, Ga. (WTOC) - In this Summer Science experiment Bailey, Lily, Ella and Reese show us how red cabbage can be used to test how acidic different liquids are. When the indicator touches ...
Scientists use a scale called the pH scale to measure how acidic or basic something is. The scale runs from 0 to 14. Where 0 is the most acidic and 14 is the most basic. Around the middle we have ...
Place 150 mL of water and 100 mL of Milk of Magnesia in a 500 mL beaker. Then add about 10 mL of your universal indicator or cabbage juice. Use the stir plate to start stirring your solution, or you ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...
Nearly everything at [HAD] is at least based on science in some way or another. If, however, you would like to do some actual scientific experiments with stuff around the house, [Observationsblog] ...
