| Question | Answer |
|---|---|
| Substance that has more OH- ions than H+ ions? | base |
| Mixtures of water and non-dissolved material, such as blood | suspension |
| A material composed of two or more elements or compounds that are physically mixed, but not chemically combined | mixture |
| the substance dissolved is called | solute |
| Type of bond formed when one or more electrons are tranferred(given away or accepted) by an atom | ionic |
| Attraction between molecules of same substance | cohesion |
| Subatomic particles with a negative charge | electron |
| Type of bond that is weaker than ionic or covalent bonds but bonds one water molecule to another | hydrogen |
| Substance in which the solute dissolves | solvent |
| Atoms of the same element that differ in the number of neutrons they have | isotopes |
| Weak acids or bases that can react with strong acids or bases to prevent sharp, sudden change in ph | buffer |
| A mixture in which two or more substances are evenly dispersed | solution |
| Type of bond formed when eletrons are shared between atoms | covalent |
| The uneven distribution of electrons | polarity |
| Attraction between molecules of different substances such as water and a window | adhesion |
| This measures the amount of hydrogen ions in a substance | pH |
