00:01 So the ph of a solution is the negative logarithm of the hydronium ion concentration present in a solution.

00:10 So the ph range of a solution can lie between 1 to 14.

00:17 So the highest possible value of ph is 14 and the lowest possible value of ph is 1.

00:24 Now if a solution has low ph that is lying between 1 to 5 then the solution is acidic in nature.

00:37 If the ph of the solution lies between 6 to 7 then it is neutral.

00:42 And if the ph is high that is lying between 8 to 14 then the solution is basic or alkaline in nature.

00:56 Now, there is something called a ph paper.

01:02 Now, this ph paper acts like an indicator.

01:06 So, depending upon the color of this ph paper, we can determine the ph of a solution.

01:13 So if you dip a ph paper in a solution, then it will change its color to change a change.

01:21 So if we dip a ph paper in a solution, then it will change its color.

01:25 And depending upon that color we can determine the ph of the solution because each color corresponds to a particular ph.

01:35 So now if we go through the diagram given in the question, so this is the diagram.

01:44 So we can see that each color of the ph indicator is indicating a particular ph.

01:52 So depending upon the color, we can determine the ph of the size...
