Question

Андрей и Света опытным путём выявили, что в пробирке № 1 присутствуют сульфат-ион и катион водорода, а в пробирке № 2 присутствуют сульфат-ион и катион аммония. Света сделала вывод о том, что в двух пробирках содержатся соли, Андрей считает, что в них находятся кислоты. В чём неправы Андрей и Света? Что находится в пробирках № 1 и № 2? Ответ поясните.

Answer 1

В 1 пробирке находится кислота H₂SO₃

Во второй пробирке содержится соль (NH₄)₂SO₃

Света неправа в том, что там кислоты , соственно и Егор тоже

Answer 2

What is present in test tubes #1 and #2?

Andrey and Svetlana have conducted an experiment and observed the following:

- Test tube #1 contains sulfate ions and hydrogen cations. - Test tube #2 contains sulfate ions and ammonium cations.

Based on these observations, Svetlana concluded that both test tubes contain salts, while Andrey believes that they contain acids.

What is the correct interpretation?

Svetlana's conclusion that both test tubes contain salts is correct, while Andrey's belief that they contain acids is incorrect.

In test tube #1, the presence of sulfate ions (SO4^2-) and hydrogen cations (H+) indicates the formation of an acid. The sulfate ion is the conjugate base of sulfuric acid (H2SO4), and the hydrogen cation is characteristic of acidic solutions. Therefore, test tube #1 contains an acid.

In test tube #2, the presence of sulfate ions (SO4^2-) and ammonium cations (NH4+) indicates the formation of a salt. The sulfate ion is the conjugate base of sulfuric acid (H2SO4), and the ammonium cation is the conjugate acid of ammonia (NH3). When an acid reacts with a base, a salt is formed. In this case, the reaction between sulfuric acid and ammonia results in the formation of ammonium sulfate (NH4)2SO4. Therefore, test tube #2 contains a salt.

To summarize: - Test tube #1 contains an acid. - Test tube #2 contains a salt, specifically ammonium sulfate.
