Kevin Chen Part 3 Ap Chemistry
I have completed this assignment on my own. I have not discussed this assignment with anyone except Ms. Chubbuck. I have neither given nor received assistance in completing these tasks. Kevin Chen
1). How to fold filter paper and how to filter a solid from a solution: Gravity Filtration: Select the correct size of filter paper and fold the filter paper into a cone by folding it in half and then again.
Place the filter paper in the opening of the Erlenmeyer flask, wet the paper with a little of the solution, and pour the solution.

The process for making solutions of a given molarity from a solid solute: In cases where the solution requires a compound that is not usually stored in the stockroom, such as pure hydrogen chloride, a different concentrated solution of the one needed can be used. For example to achieve 2.00 M of hydrochloric acid, one can use 12.00 M of hydrochloric acid. When the solute can be easily obtained, one can simply use the solute and mix it with water.

Explain: Never add water to acid, rather, always add acid to water because acid reacts violently with water and when water is initially added to acid, the solution begins as a concentrated solution of acid and will heat up, boil, and splash out of the container. However, if acid is added to water, the solution begins as a very diluted solution and will release heat in small amounts.
