Alina is on a distinguished road
Grade 12 chemistry question


I need help with the following question:

Write a procedure that would follow to demonstrate the effect of increasingly higher concentrations of hydrochloric acid on its rate of reaction with antacid tablets. Can only use materials listed:
- Hydrochloric acid (with a concentration of 1.0 mol/L)
- Distilled water
- Antacid tablets (calcium carbonate)
- A mortar and pestle
- Graduated cylinders (10 mL, 100 mL sizes)
- Test tubes and beakers
- Balance and measuring pan
- Hot plate (heat source)
- Thermometer
- Stopwatch or other timing device
- Ice-water bath
- Scoop

I realize that hydrochloric acid needs to be diluted with water in 4 beakers. Each beaker will contain different amount of HCL in it. Im having a hard with starting the procedure please assist.
