Ammonium ions (NH_4^+) must be removed from a mixture during the detection of sodium (Na^+) and potassium (K^+) cations of the first analytical group. Why is it necessary?

Question

Answer

Ammonium salts decompose at high  temperatures

Answer

The solution pH becomes >7, because of hydrolysis of these ions

Answer

Compounds with K^+ and Na^+ ions  form supersaturated solutions

Answer

They interfere with the determination  of potassium and sodium ions

Answer

The solution pH becomes <7, because of hydrolysis of these ions
