A chemical procedure where a substance of known and unknown concentrations react in a reaction with known stoichiometry 2. What is the purpose of titration? Titration is used to test the effectiveness of products such as bleach. Titration fixes the imbalance of concentration levels....
Amixtureis what you get when you combine twosubstancesin such a way that nochemical reactionoccurs between the components, and you can separate them again. In a mixture, each component maintains its own chemical identity. Typically mechanical blending combines components of a mixture, although other...
