Explanation:
<h3> the atomic mass is the number of protons and neutrons in an element added together</h3>
pH of the solution is calculated using the following formula:
Here, is concentration of hydrogen ion.
Initial value of pH is 6.7, calculate concentration of hydrogen ion from this as follows:
Putting the value,
Thus, initial concentration of hydrogen ion is .
Now, final pH value is 8.7, calculate concentration of hydrogen ion as follows:
Thus, final concentration of hydrogen ion is .
The ratio of final to initial value will be:
Thus, if pH increases from 6.7 to 8.7, concentration of hydrogen ion becomes of the initial value.
