Making A Salt From An Insoluble Metal Oxide

Question 1

What is step 1 of making a salt from an insoluble metal oxide experiment?

Answer 1

1- we add enough of the insoluble metal oxide to the acid to ensure that all of the acid had been NEUTRALISED

Question 2

What is the second step in the making a salt from an insoluble metal oxide experiment?

Answer 2

2- we can tell when the reaction is complete when no more of the METAL OXIDE dissolves- we say metal oxide is “in excess”

Question 3

What is the third step in the making a salt from an insoluble metal oxide experiment?

Answer 3

3- the excess insoluble oxide is filtered out to leave a SALT SOLUTION

Question 4

What is the fourth (final step) of the making a salt from an insoluble metal oxide experiment?

Answer 4

4- the SALT SOLUTION is gently heated to evaporate some of the water and then left to cool+ CRYSTALLISE
