Answer Details
When ethyne, also known as acetylene, reacts with an acidic solution of potassium tetraoxomanganate (VII), also known as potassium permanganate, a chemical reaction occurs. The purple colour of the potassium permanganate solution fades away, and the solution becomes colourless. This happens because the potassium permanganate oxidizes the ethyne, which breaks down into carbon dioxide and water. This reaction converts the potassium permanganate into manganese(II) ions, which are colourless, hence the colour of the solution changes from purple to colourless. Therefore, the correct answer is "colourless."
