When mixing disinfectant and water, which is the correct order?

1. Mix them equally

2. Pour water into disinfectant

3. Pour disinfectant into water

4. Combine them simultaneously

The correct answer is: Pour disinfectant into water

Pouring disinfectant into water is the correct method because it helps to prevent splashing and ensures that the disinfectant is diluted evenly. When the concentrated disinfectant is added to the water, it allows for a more controlled mixing process, reducing the risk of creating a hazardous situation where fumes may escape or the liquid may bubble violently. This method also ensures that the disinfectant can effectively dissolve and disperse within the water, providing the proper concentration needed for effective sanitation. The other methods, such as mixing them equally or combining them simultaneously, may not provide the same level of safety or effectiveness. Pouring water into disinfectant can lead to a more hazardous scenario, where the concentrated solution reacts violently or splashes back. Proper technique is crucial in ensuring both safety and effectiveness when preparing disinfectant solutions.
