Hey guys I'm little late. On Friday we had sub teacher, Mrs. Zalatimo, and we start separation Lab Part B. Each group hadfollowed their Procedure which was homework.
For this lab we were going to separate heterogeneous Mixture iron, sand, and salt. I measure each of masses and calculate percentage.
Most of groups used magnet to take out iron. Then, we mixed the mixture with water and used the filter paper to take out sand.
Then, most of the groups heat the filter paper to take out moist from sand. After that we could easily measure the mass of sand and subtracted each mass of iron and sand from total mass.
However, some of the group triedto boil the left liquid which is mixture of water and salt to find salt. I thought this was going to work and we can find the salt, but the water started explode and we couldnt get salt.
Our homework over the weekend is to answer the post lab questions from Separation Lab and pre lab question from What Chemical Reaction Lab.
Boiled salt
