1. The difference between detergents and soaps is that detergents can be used in hard water.
2. Salts are made from bases and esters come from alcohols that are not bases but hae a hydroxyl group.
3. Polyesters are synthetic fibers that are made from an organic acid that has two -COOH groups and an alcohol that has tow -OH groups.
4. Titration is a process in which a solution of a known concentration is used to determine the concentration is used to determine the concentration of another solution.
5. The endpoint of titration occurs when a drop f base turns the acid solution pink and the color persists.
6. Soap has a polar end that easily mixes with oil and dirt.
7. During a neutralization reaction, hydronium ions from an acid combine with hydroxide ions from a base to produce water and a salt.
8. A salt is a compound formed when the negatie ions form an acid combine with the positive ions form a base.
9. In titration, the solution of the known concentration is called the standard solution.
