The pH scale is a measure of how acidic a solution is.
<h3>What is a pH scale?</h3>
The unit of measurement to determine how acidic or basic a solution is, is done via a pH scale, which ranged from 0 to 14, on which 0 to 6.9 means that the solution is acidic, and 7 is neutral.
Hence, the pH scale helps to determine the acidic amount of the solution.

The required graph for a single variable is a linear graph or time series graph
<h3>Single variable graph</h3>
A single variable graph is a graph having an input and one output.
For instance, the equation of a line y = mx + b is a single variable graph.
Hence the type of data for a single variable graph will give a linear function. Therefore the required graph for a single variable is a linear graph or time series graph
