Alka Seltzer Lab
Aim – To compare the mass of the products of a chemical reaction with the mass of its reactants.
Hypothesis- The total mass should increase
Materials –
1x Safety glasses.
250ml conical flask.
4x Alka-Seltzer tablets.
1x Balloon.
Matches.
1x Electronic balance.
100ml measuring cylinder.
Water.
Method –
*Place the conical flask on the balance and pour in 100ml of water.
1. Place two tablets alongside the conical flask and record the total mass.
*Remove the flask from the balance and drop the tablets into the water.
2. When the reaction is complete, weigh the flask and record the mass.
*Rinse out the flask thoroughly and again add 100ml of water.
* Place two tablets inside the balloon. You may need to break the tablets into pieces to do …show more content…
- The results show that before placing the Alka-Seltzer tablets Into the conical flask the mass does not slowly change until the Alka-Seltzer tablets are released into the water to start the chemical reaction (tablets dissolving) and as the tablets dissolve, gasses are released (carbon dioxide), which makes the total mass increase. In test one without the balloon the total mass increased by 4.88grams and in test two with the balloon the total mass increased by 7.73grams, this shows that when the balloon is placed over the conical flask that gases from the tablets are released and concealed within the balloon and greatly increases the total mass.
- The law of conservation of mass states that matter can be neither created nor destroyed during a chemical reaction, so when the tablet dissolved into the water the tablets turned from a solid into a liquid while mixing in with the water and releasing carbon dioxide. The tablets took a while to dissolve as the tablet had sodium in it, which when placed in water the dissolving of the tablet causes a strong exothermic reaction as the sodium responds with water and released carbon
