Step-by-step explanation:
Good question!
When you react an acid with a base,the pH of the product is determined by the concentrations of the reactants (the acid and the base)
If both reactants (acid and base) are strong,the pH of the product is 7
If the acid is stronger than the base,the pH of the product will be less than 7
If the base is stronger,the pH of the product will be greater than 7
I hope this helps
