The chemist in charge of Mack Produtos Químicos received a batch of ammonium hydroxide in whose invoice stipulated the 25% ammonia content. In turn, the responsible chemist collected
in an Erlenmeyer flask, previously tared, a sample weighing 0.820g. Then he added water and
methyl red and titrated it with a solution of HCl, consuming 13.05mL of this acidic solution.
It is known that the HCl solution was standardized with pure sodium carbonate (P. A.), using 1.1498g
of salt against 30 ml of acid. What is the chemist's attitude towards the batch received? justify
