Method

1. Using a clean container, carefully collect water from the different sources.
2. Label the container with the information - how you get the water (for example: tap, water fountain, bottled), where you get the water and the city.
3. Make an Observation Chart like this:

   Water Source Location	Chlorine Test	pH Test	Acid Demand	Total Alkalinity	Water Hardness

4. Test the sample of water for chlorine.
   • Pour water in vial
   • Add 5 drops of Solution 1.
   • Observe the colour after a few seconds, and compare to standard test colours.
   • Observe the colour after about a minute, and compare to standard test colours.
   • Write the observations and colour number on your chart.
5. Test the sample of water for pH.
   • Pour water in vial
   • Add 1 drops of Solution 4. Swirl.
   • Add 5 drops of Solution 2. Swirl.
   • Observe the colour after about a minute, and compare to standard test colours.
   • Write your observations and colour number on your chart.
6. Test the sample of water for Acidity.
   • Use sample water from pH.
   • Add Solution 3, drop by drop.
   • Count each drop until the colour is 7.6
   • Write down how many drops were used.
7. Test the sample of water for Alkalinity.
   • Pour water in vial
   • Add 1 drops of Solution 4. Swirl.
   • Add 1 drops of Solution 5. Swirl.
   • Add Solution 3 drop by drop.
   • Count each drop until the colour is clear or yellow.
   • Write down how many drops were used.
8. Test the sample of water for Water hardness.
   • Pour 20ml water into a clean container.
   • Add 1 teaspoon of Ivory Snow soap.
   • Close the container very tightly.
   • Shake vigorously to make lots of bubbles.
   • Using the ruler, measure the level of bubbles.
   • Write your observations on your chart.
