Bleach has a strong material on it. Bleach can clean water but it makes the litmus Paper white because it Contained too much Bleach. Bleach can make a cloth teared apart if it has a lot Of amount Of Bleach. It's pH is 7, but because we used Litmus Paper we can't know the pH exactly . If we used pH meter, it would be 7 or up. 7 is neutral. 0-6 is an Acid and 8-14 is a Base. Maybe the pH would be more than 7 because the criteria of a clean Water is no Color, no odor, and erm, i Forgot :D It has a strong Odor there so it's not Consumable to be drink. Last week, we collected rain Water and the pH is 4. Maybe because the Industries in Batam. But dont worry at all, 4 is not a Strong Acid. But Last last week, it's pH is 5.
Oh bye !!

i learned that bleach can clean water but it makes the litmus paper white. although it cleans how can we drink ? we tried the other experiment with sand it somehow works . It's pH is 7 so then we tried to taste it. . the criteria of a clean water is no color, no smell, and one more . but our water smells like eww. somehow like that huh? we collect the that time rain water. really we're surprised that it is pH 4 'cause the last last last week/ maybe day it is always pH 5 but now it's 4. Oh my gosh.:p

bye !
