What are the two carbonates in baking soda? we are Wendy,Lily,Alice and mollie.

[|Our elearning blog]

The two carbonates in baking soda are sodum aind calcium carbonate. (baking soda) ||
 * = **Ask a Question and List Possible Variables for Testing** ||
 * **What we want to find out:** || what the two carbonates are in bicarbonates of soda
 * **Things we could find out:** || where baking soda is made ||
 * **Things we could measure:** || the different amounts of the two carbonates ||
 * = **Select one variable to investigate and measure. Keep the rest the same.** ||

bicabonate of soda || carbonates in baking soda ||
 * = **Choose a Variable** ||
 * **We will change:** || we will change ||
 * **We will measure:** || how much carbonate is in
 * **The rest we will keep the same:** || yes because ther is only two

the reaction || be a little bit stronger || in with it to make the reaction smaller ||
 * = **Ask a Question and Make a Prediction** ||
 * **When we change:** || the acid ||
 * **What will happen to:** || the strength of
 * **Make a prediction:** || the reaction will
 * **Because:** || there is stuff is mixed


 * = **Make a Plan of How to Carry out the Investigation** ||
 * **List the equipment:** || # one box of baking soda
 * 1) two cups
 * 2) a tea spoon
 * 3) vinegar
 * 4) lemon
 * 5) oranges ||
 * **What we are going to do:** || # we are going to read the ingredients.
 * 1) then we will buy the two carbonates in baking soda
 * 2) use other acids to see if the reaction is stronger or weaker

the acids to either lemon juice or orange juice. || needed. || didnt react. salt and lemon juice didnt react. salt and calcium did react with vinagar. ||
 * = **Record Your Results** ||
 * **What we changed:** || we changed
 * **What we measured:** || how much orange juice we
 * **Results:** || lemon juice and calcium
