Prepare Carbon dioxide Test for Carbon dioxide. Write 3 uses and properties of CO2

• Limewater (calcium hydroxide solution, $\text{Ca(OH)}_2(\text{aq})$)
• A source of carbon dioxide, such as calcium carbonate ($\text{CaCO}_3(\text{s})$) and a dilute acid (e.g., hydrochloric acid, $\text{HCl}(\text{aq})$) if generating it, or simply exhaled breath.

• Test tube or beaker (to hold the limewater)
• Delivery tube or straw (to bubble the gas through the limewater)
• Conical flask or gas generator (if generating $\text{CO}_2$ from chemicals)
• Stopper (for the conical flask/gas generator)

The materials for the Carbon Dioxide Test are:

• Limewater ($\text{Ca(OH)}_2(\text{aq})$)
• Test tube or beaker
• Delivery tube or straw
• Calcium carbonate ($\text{CaCO}_3(\text{s})$) (if generating $\text{CO}_2$)
• Dilute hydrochloric acid ($\text{HCl}(\text{aq})$) (if generating $\text{CO}_2$)
• Conical flask and stopper (if generating $\text{CO}_2$)
