Answer:
11.3 g of are produced from 36.0 g of
Explanation:
1. The balanced chemical equation is the following:
2. Use the molar mass of the , the molar mass of the and the stoichiometry of the balanced chemical reaction to find how many grams of are produced:
Molar mass = 18
Molar mass = 17
Therefore 11.3 g of are produced from 36.0 g of
Answer:
The Ka value used for the buffer system is :- Ka2 = pKa2 = 7.2
pH = 7.1
Explanation:
The buffer system given in the question is :-
and
The reaction taking place is:-
The Ka value used for the buffer system is :- Ka2 = pKa2 = 7.2
The pH can be calculated as:-
pH = 7.2 + log 0.40/0.50 = 7.1
