Question: 1 / 400

A 20 percent sodium hypochlorite is what percent if water?

60 percent

70 percent

80 percent

Sodium hypochlorite is a chemical compound that is commonly used as a disinfectant and bleaching agent. The question is asking what percentage of the solution is water, given that the solution is 20% sodium hypochlorite.

Option A, B, and D are incorrect because they suggest a higher concentration of sodium hypochlorite. A 60% solution would have more sodium hypochlorite than water, a 70% solution would have even more, and a 90% solution would be almost entirely sodium hypochlorite. These concentrations would not match the given information that the solution is 20% sodium hypochlorite.

Option C is the correct answer because it suggests a lower concentration of sodium hypochlorite, meaning that the majority of the solution is water. This aligns with the given information that the solution is 20% sodium hypochlorite, leaving the remaining 80% as water.
