Transcript

00:01 Students let me explain you the question here we have to consider some common drinks so what are those common drinks that is alkaline water alkaline water so alkaline water ph it is 8 fruit juice fruit juice ph value 6 .8 then get a rate so get a rate ph it is 3 and green tea vinegar 3 .5 these are the ph values we have to organize these foods from most basic to most acidic most basic to most acidic we have to arrange them so whenever we see the ph scale so the ph scale it ranges from 1 to 14 so 1 2 3 4 5 6 7 7 8, 9, 10, 11, 12, 13, 14.

01:12 So here the one, it means strong acid, strong acid.

01:19 7 means neutral, neutral.

01:23 14 means strong base, strong base.

01:29 So here, 8, 9, here it is weak base.

01:36 Big base.

01:39 So here 5, 6, these are weak acids.

01:44 Weak acid.

01:45 Whenever we approve the values here, so alkaline water, 8.

01:51 So alkaline water, alkaline water, then 9, it is green tea, green tea, then fruit juice 6 .8, fruit juice, 6 .8, fruit juice, 6 .5.

02:11 Then gatorade 3 gatorade 3 vinegar 3 .5 vinegar 3 .5 so these are the ph range so we here we have to arrange from most basic to most basic to most acidic most acidic so most basic that means the basic value increases like this so here what is the most basic so here that means higher ph value then it will be most basic so here nine that is green tea it is most basic then after green tea alkaline water alkaline water then fruit juice then fruit juice then vinegar vinegar to getroid so this is most most basic to the most acidic.

03:17 We have to start from here to this direction...
