A
Metal Oxide, Metal Hydroxide & Metal Carbonates
Reactions are exothermic
2
Q

A
Metal Oxide, Metal Hydroxide
3
Q
When acid react with bases/alkalis is called…
A
Neutralisation
4
Q
Give the equation for base?
A
Acid + Base - Metal Salt + Water
5
Q
Give the equation for Alkali?
A
Acid + Alkali - Metal Salt + Water
6
Q
What is the test for Carbonate?
A
Add acid and if bubble come off producing CO2 it is a Carbonate
7
Q
Give the equation for Metal Carbonates?
A
Acid + Metal Carbonate - Metal Salt + Water + Carbon Dioxide
8
Q
What is the chemical test for limewater?
A
Is to pass Carbon Dioxide through limewater. Turns Cloudy and forms White Precipitate
9
Q
How to form Crystals?
A
- Warm the salt solution to evaporate the water. You get larger crystals if you evaporate the water slowly.
- You filter the mixture to remove the excess base, then evaporate the water in the filtrate to leave the salt behind.
