Question

A scientist in new York has been measuring the pH of rainfall in that state for the last 10 years. He has determined that the pH of rainfall from 4.22 to 4.40. Therefore, the most acidic rainfall in the state is

Answer 1

Answer:

4.22

Explanation:

pH scale ranges from 0-14. 0-7 being the acidic range with 0 being the most acidic, 7 -14 is the basic range with 14 being the most basic.

Answer 2

Answer:

The most acidic rainfall is 4.22.

Explanation:

An acid is a substance is that produces  hydrogen ion in an aqueous solution. Increasing hydrogen ion contents depict increase in acidic contents.

An Alkaline is a substance that produces hydroxide ion in an aqueous solution. Increasing hydroxide ion depicts increase in alkalinity.

Using a pH scales to measure the acidity or alkalinity of a substance has a range value of 0 to 14 . Decreasing pH value depict increasing acidity contents . 0 to 2 is very acidic 3 to 5 is moderately acidic and so on . 7 pH scale means the substance is neutral . From 7 upward depict increasing alkalinity.

Since the pH of rainfall change from 4.22 to 4.40 that means the acidic content  decrease. The most acidic rainfall is 4.22.
