🤓 Based on our data, we think this question is relevant for Professor Goodey's class at TAMU.

Solution: A change in pH of 1.0 unit indicates that: 1. the volume of H+ in a solution changes by an order of magnitude.2. the acid or base content decreases or increases by 0.1 M.3. the molarity of H+ changes by one order of magnitude.4. the acid or base content decreases or increases by 1.0 M.5. the salt content decreases or increases by 1.0 M.

Problem

A change in pH of 1.0 unit indicates that: 

1. the volume of H+ in a solution changes by an order of magnitude.

2. the acid or base content decreases or increases by 0.1 M.

3. the molarity of H+ changes by one order of magnitude.

4. the acid or base content decreases or increases by 1.0 M.

5. the salt content decreases or increases by 1.0 M.

Solution

We’re being asked what is indicated by a change in pH by 1 unit.  Recall that pH is given by:



A change in pH of 1.0 unit indicates that:
