PROPERTIES OF SOLUTIONS

Reading the pH scale. Match the substances on the left with the pH on the right. Use the pH scales above for help. battery acid pH 0 drain cleaner pH 14 milk pH 6 bleach pH 13 bananas pH 5 Reading the pH scale. Determining if substances are acids or bases. Select from the list and place the substances in the correct column. ACIDS vinegar apple lemon BASES blood baking soda drain cleaner Which substance is the solute and which substance is the solvent? Write the words: solvent or solute solute solvent Choose a word from the word bank to complete the following passage about solutions. 1. Solubility is the amount of solute dissolved in a solvent at a given temperature.2. When a solution can dissolve more solute, it is considered unsaturated. 3. A solution is saturated when too much solute has been added and cannot be dissolved any further. 4. A supersaturated solution will only dissolve the excess solute if the solution is heated. Solid crystals will form when the solution cools down. SOLUBILITY Identify the following solutions in the test tubes as: supersaturated, unsaturated, or saturated. PLEASE WRITE THE WORDS EXACTLY HOW THEY ARE WRITTEN IN THESE DIRECTIONS. saturated supersaturated A substance that dissolves the solute to form a solution. dilution acid solvent pH means-- possibility of hydrogen power of hydrogen protons present in solution The solubility of a solute can be increased by: (there is more than one answer) stirring or agitating the solution heating the solution increasing the surface area of the solute In a solution of sugar and water: the water is the solute, and sugar is the solvent both the sugar and the water are solvents the sugar is the solute, and the water is the solvent A substance that dissolves in a water to form a solution that conducts an electric current is said to be an: electrolyte nonelectrolyte Which of the following should most greatly increase the rate of dissolving of a salt in water? Increasing the temperature and stirring Decreasing the temperature and stirring
