Answer: 2) Chloroform & Caustic potash
Explanation:
The carbylamine reaction is a kind of chemical test which is done to detect primary amines in an unknown solution. It cannot detect secondary and tertiary amines.
The reaction involves the heating with up of the unknown solution with alcoholic potassium hydroxide or caustic potash and the chloroform.
In the presence of primary amine, the production of isocyanide results.
Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.
Given chemical reaction is:
BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄
Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.
Hence the required coefficients is 1.
