Will C6H8O7 react with water?

What will happen?

Was there a reaction?

•What is your evidence?

•What caused the bubbling and fizzing?

How will you capture the

gas?

How much sodium bicarbonate was in the

reaction bottle?

How much citric acid was in the reaction bottle?

How much citric acid did you put in your stock

solution?

•One 2-mL spoonful•Added to 100 mL of water

•Made 20 5 mL samples

How much citric acid was in the reaction bottle?

Yikes! We have to do

math in science?
