Proton is a positively charged particle
To minimize the sharp pH shift that occurs when a strong acid is added to a solution, IT IS PRACTICAL TO ADD A WEAK BASE.
When a strong acid is added to a solution, it usually brings about a sharp change in the pH of the concerned solution. To avoid this, one can add a weak base to the solution first. The weak base will serves as a buffer for the strong acid and prevents the solution from experiencing sharp pH variations.
Answer:
Isotopes of an element have the same number of protons but have different numbers of neutrons in their nuclei. The mass number is the sum of the numbers of protons and neutrons in the nucleus of an atom.
