test for carbonates Flashcards
1
Q
what do carbonates all contain?
A
the carbonate ion, CO3 2-
2
Q
what the basic test include?
A
The test for this ion involves adding dilute acid and testing the gas released
3
Q
if the carbonate compound is present what will we see?
A
If a carbonate compound is present then effervescence should be seen and the gas produced is CO2 which forms a white precipitate of calcium carbonate when bubbled through limewater
Limewater turns milky in the presence of CO2 caused by formation of insoluble calcium carbonate
4
Q
which other product other than CO2 does this reaction make?
A
water
