A buffer with a pH of 4.00 contains 0.19 M of sodium benzoate and 0.30 M of benzoic acid. What is the concentration of [H3O ] in the solution after the addition of 0.052 mol HCl to a final volume of 1.3 L

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

answer: e.   sour taste
