The students of 1C2 used a pH meter to measure the pH of the water taken from the taps at home. A total of 40 pupils conducted the test. The results are shown in the line graph below.

Based on the line graph, it is quite evident that the pH value of the water from most homes ranges between 6.51 and 7.00. And as none of the pH values hit 8.00, we can thus conclude that water in Singapore is safe for drinking. Reason being that weak acids are safe for consuming.
