- Chemistry Chapter 6 - Part 2
- Metal Carbonates
- Metal carbonate + acid = a salt + water + CO2
- eg. calcium carbonate + hydrochloric acid = calcium chloride + water +carbon dioxide
- Limestone (alkaline) is mainly calcium carbonate
- Limestone is used to make cement and glass
- And to control acidity in soil
- Limestone is used to make cement and glass
- Test for carbon dioxide = milky limewater
- Limewater is alkaline and CO2 is acid so they react and form tiny insoluble particles that don't let let through
- Metal carbonate + acid = a salt + water + CO2
- Thermal decomp. of carbonates
- Calcium carbonate decomposes if we heat it
- This produces quicklime
- Calcium carbonate decomposes if we heat it
- Titrations
- Left over = in excess
- End point = when both the acid and alkali are completely neutralised
- Metal Carbonates
