Wondering: i know that salt eats away at ice so would any other powder substance eat ice

Hypothesis: i think that baking soda will melt ice the quickest 

Materials: salt baking soda citric acid sugar 5 same size containers with half a cup of Frozen water frozen overnight

Variables: 

Control:      the amount of powder and the water

Dependent:     the powder that you use

Independent:     how quickly the ice melts and what powder melts the ice the quickest

Procedure:  

Put  ½ cup water in the 5 containers in the freezer

put ¼ cup of the powders on the ice 

Wait until ice melts

Results/Observations: I observed that the ice underneath the salt was melting the fastest and the sand was melting the slowest and the others were  behind the salt by a bit

Conclusion: This is why the salt melted the fastest out of them all,  when the salt is put on the ice the lowers the freezing rate of the water so it speeds up the process of the ice melting, a real-life example is when frosts happen you could put some salt on it and the roads and the footpath and it won't be as slippery any more for cars or people and not as dangerous. 

This is my literacy for the week we watched ice melt with different powders the powder were sand, salt, sugar, baking soda, and citric acid.

have you ever done an experament like this?
