Answer:

Caustic soda is the odd one out.

Explanation:

Caustic soda is the odd one out. This is because the remaining two are related to each other. Iodine is used to test the presence of starch in any given substance.

Answer:

Urea is neither acid nor base so it's odd one out.

Explanation:

Iodine- Iodine is a Lewis acid. Aqueous hydrogen iodide is known as hydroiodic acid, which is a strong acid.

Starch- Although starch is a weak acid, it is more powerful than water. When sodium hydroxide is added to a starch slurry, the starch will react and the viscosity of the slurry will alter as a result.

UREA formed by combining two ammonia molecules (NH3) with a carbon dioxide (CO2) molecule in the urea cycle. Dissolved in water, it is neither acidic nor basic .Purple is the colour that urea causes on litmus paper. With an acidic solution, litmus paper turns red; with a basic solution, it turns blue. When we tested urea on a litmus paper, it became purple, demonstrating its neutral nature.

Washing Soda- Since it separates into the strong alkali (potassium hydroxide) and the weak acid (carbonic acid) when it is dissolved in water, washing soda is basic in nature (sodium hydroxide). Any solution that contains sodium carbonate will quickly react when that substance is introduced, releasing hydrogen gas in the process.

Given: Iodine, urea, Washing Soda, Starch

Find: Which is the odd one

Urea is neither acid nor base so it's odd one out.
