The graph that models the pH of this solution is graph A.
<h3>What is a graph?</h3>
It should be noted that a graph is a diagram such as a series of one or more points, lines, line segments, curves, or areas which represents the variation of a variable in comparison with that of one or more other variables.
The pH is a measure of how acidic or basic water is. It should be noted that the range goes from 0 - 14, with 7 being neutral. The pHs of less than 7 indicate acidity, while a pH of greater than 7 indicates a base. The pH is really a measure of the relative amount of free hydrogen and hydroxyl ions that are in the water.
In this case, x represents the concentration of the hydrogen ions. The first graph illustrates this.

<u>Complete question:</u>
The ph of a particular solution is given by pH=-log(x-2) where x represents the concentration of the hydrogen ions in the solution in moles per liter. Which graph models the ph of this solution?
Answer:
0.166667 - Common Ratio
step by step
Formula Used: Common Ratio=First term/Consecutive Term
Calculation: 0.166667=(-14)/(-84)
2.3 would be 2+(3/10), which we would then use a common denominator of 10 to get 20/10+3/10=23/10. 5.06 would be 5+(6/100). 6/100 can be reduced by a factor of 2 to 3/50, which we would then use a common denominator of 50 to get 250/50+3/50=253/50. As a fraction multiplication problem, this would look as (23/10)(253/50)
