Answer: pH in Water The acidity or alkalinity of a

Problem 17AYU

Answer:

Step1:

We have The acidity or alkalinity of a solution is measured using pH. A pH less than 7 is acidic, while a pH greater than 7 is alkaline. The following data represent the pH in samples of bottled water and tap water.

a).

Maximum value in Tap = 7.69

Minimum value of Tap  = 7.1

Now,

Range = maximum value - minimum value

          = 7.69 - 7.1

       R = 0.59.

Similarly,

 Maximum value in Bottled = 5.28

Minimum value of Bottled  = 5.02

Now,

Range = maximum value - minimum value

          = 5.28 - 5.02

       R = 0.26.

Therefore, By comparing both measure of dispersion we can say Tap type of water has more dispersion in pH using the range as the measure of dispersion.
