I don't think so, but if you have it they will most likely look into it.
The pH of the substance is 3.3 which is acidic.
<h3>What is pH?</h3>
The pH of a substance or solution is referred to the degree of acidity or alkalinity of that substance. It is measured on a scale of 0 -14.
Given the concentration of hydrogen ions as 5. 0 × 10–4 moles per liter,we use the formulae
ph = –log[h+]
plugging in thge value of h+ as 5. 0 × 10–4 moles per liter we have:
pH = –log{5. 0 × 10–4 ]
pH=3.3

The point 
is on the graph.
<h3>Procedure - Inverse variation</h3><h3 /><h3>Inverse variation model</h3><h3 />
An <em>inverse</em> variation is represented by the following formula:
(1)
Where:
- Independent variable.
- Dependent variable.
- Proportionality constant.
We can eliminate the proportionality constant by creating the following relationship:
(2)
<h3>Determination of another point</h3>
If we know that 
, 
and 
, then the remaining variable is:
The point is on the graph. (Correct choice: C)
