Explanation:
Considering the Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution as:
Where Ka is the dissociation constant of the acid.
pKa of phenolphthalein = 9.40
pH = 10.9
So,
An electron has a negative charge of one
An neutron has no charge (hence, neutral)
An proton has a positive charge of one
