1. When a non-metallic oxide reacts with water, a base will be formed as the product of the reaction. When a metallic oxide like phosphorous pentoxide reacts with water, a base will be formed as the product of the reaction.
2. When water is mixed with oxides, hydrogen gas is evolved. A red to blue color change in the litmus paper indicates that the solution tested is an acid.
3. The filtrate in any filtration process is left on the surface of the filter paper, while the residue is collected at the bottom of the flask/container after passing through the filter paper. In the distillation process, the methyl violet served as a compound to acidify the water.
4. In the Winkler Titration Method, the starch solution turns colorless in the presence of free iodine in the solution to be titrated. In the Winkler Titration Method, the endpoint is determined by the visual indicator, methyl violet.
5. Nuclear fission takes place inside a reactor to produce nuclear energy. Uranium is not radioactive.
