Sodium hydroxide in water gives A. yellow colour solutionB. green colour solutionC. colourless solutionD. light pink solution
Sodium hydroxide (NaOH) is a strong base that is highly soluble in water. When sodium hydroxide dissolves in water, it dissociates into sodium ions (Na⁺) and hydroxide ions (OH⁻).
The correct answer is C. colorless solution. When sodium hydroxide is dissolved in water, it forms a transparent, colorless solution. Sodium hydroxide itself is a white solid, and its dissolution in water does not impart any color to the solution.
