Mystery Mixture Lab Report

During our chemistry unit, we had to identify different types of compounds in a mystery mixture. I have identified 2 compounds in the mystery mixture. From the physical appearance of the mystery mixture, it seems that there are only 2 types of compounds. You could see that there were only 2 because 1 of the compounds was very fine and powdery, while the other one was sandy and crystallized. I have determined the compounds in the mystery mixture to be citric acid and sodium bicarbonate because they have the same chemical reaction and the same physical appearance.
The 2 compounds both have unique physical properties. The first compound is crystallized and very gritty, almost like sand. The particles were translucent and about the size of a
