This section shows how the relationship between temperature and dissolved oxygen concentration affects aquatic life. 1. Dissolved oxygen concentration is based on the solubility of molecular oxygen in water. Unlike solids, which are more soluble in warmer water than cooler water, molecular oxygen is a gas. Gases are less soluble as the temperature of the solvent (in this case, water) increases. Based on this information and the previous experiment which of the following would hold more dissolved oxygen? Water at 18°C Water at 60°C Water at 37°C Water at 55°C

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
