IV: The different metals used with the diluted acid

DV: The amount of heat given of the test tube

Controlled Variable: The controlled variable is the amount of diluted acid in each test tube

Discussion: My partner and I discussed that the magnesium gave up way more heat than the zinc. As soon as we put the magnesium in the diluted acid, we got an immediate reaction. Compared to the zinc where a couple of minutes were need.

Data: 

Zinc: The zinc had black pieces of impurities let.

Apart from that it had the same looks as regular salt. Even though the Zinc salt had the looks of table salt it did not have the same taste. IT had the taste of extremely unripe banana.

Magnesium: The magnesium salt had the salt appearance as table salt. Though, like the zinc salt it did not have the same taste. It’s taste extremely bitter unlike table salt.

Based on my data I can conclude that the magnesium a bigger reaction to the diluted acid compared to the zinc due to the amount of heat each test tube gave off.
