Water and Solutions
| Question | Answer |
|---|---|
| polar | because of the uneven distribution of charge, water is called a...? |
| hydrogen bond | the force of attraction between a hydrogen molecule with a partial positive charge and another atom or molecule with a partial or full negative charge |
| cohesion | an attractive force that holds molecules of a single substance together |
| adhesion | the attractive force between two particles of different substances |
| capillarity | the attraction between molecules that results in the rise of the surface of a liquid when in contact with a solid |
| solution | a mixture in which one or more substances are uniformly distributed in another substance |
| solute | a substance dissolved in the solvent |
| solvent | the substance in which the solute is dissolved |
| concentration | the amount of solute dissolved in a fixed amount of the solution |
| saturated solution | one in which no more solute can dissolve |
| aqueous solution | solutions in which water is the solvent |
| hydroxide ion | OH- |
| hydronium ion | the hydrogen ion bonded to a molecule of water, H3O+, the form in which hydrogen ions are found in aqueous solution |
| acid | if the number of hydronium ions in a solution is greater than the number of hydroxide ions, the solution is an...? |
| base | the part of an organ nearest to its point of attachment |
| pH scale | a scale for comparing the relative concentrations of hydronium ions and hydroxide ions in a solution |
| buffers | chemical substances that neutralize small amounts of either an acid or a base added to a solution |
