Term
| What are the parts of a solution? |
|
Definition
There are 2 parts, the solute and the solvent:
Definitions:
The solute: the dissolved matter in a solution; the component of a solution that changes its state.
The solvent: a liquid substance capable of dissolving other substances.
The solvent does not change its state in forming a solution. |

Term
| What is a neutralization reaction? |
|
Definition
| A chemical reaction in which an acid and a base react to form a salt. |
|
|
Term
| Compare the characteristics of Acids. Bases, and Salts. |
|
Definition
Acid:
Taste sour
Reach with certain metals (Zn, Fe, etc.) to produce hydrogen gas
cause certain organic dyes to change color
react with limestone (CaCO3) to produce carbon dioxide
React with bases to form salts and water
base:
Taste bitter
feel slippery or soapy
react with oils and grease
cause certain organic dyes to change color
react with acids to form salts and water
Salt:
Salt is NaCl (Last letter L not I). Sodium and chloride, combined in a chemical reaction. Salt is a compound (a mixture of two or more elements). We use salt every day, in cooking or on the side walk. Salt is in everything, even in candy. |
