Acid  - a substance that produces hydronium ion when dissolved in water, Hydronium ion - positively charged ion formed when an acid desolved in water, Base - a substance that produces hydroxide ions when dissolved in water, pH - an inverse measure of the concentration of hydronium ions in a solution, Indicator - a compound that changes color at different pH values when it reacts with acidic or basic solutions, 3 properties of acids - they have a sour taste, turn litmus paper red, and react with certain metals, 3 properties of bases - they have a bitter taste, they turn litmus paper blue, and are slippery, 3 uses of acids - used as household cleaners, used in swimming pools, and used to make other chemicals, 3 uses of bases - used in toothpaste, soap, and paper, describe how the concentration of hydronium ions affects pH - As the hydronium increases the pH decreases causing the solution to become more acidic, describe the three ways scientists can test pH - Litmus paper, Look at the pH scale, The reactivity with certain metals (test with red cabbage juice), compare and contrast acids and bases - Acids have hydrogen ions (H+1), and bases have hydroxide ions (OH-1) Acids and bases are both solutions. pH of acids is less than 7; pH of bases is higher than 7; Acids have a sour taste, bases have a bitter taste, difference between hydronium and hydroxide ions and the significance of each when it comes to acids and bases - H 3O + is called a hydronium ion, and it makes things acidic. OH - is called a hydroxyl ion and it makes things basic. A solution is neutral if it contains equal concentrations of hydronium and hydroxide ions; acidic if it contains a greater concentration of hydronium ions than hydroxide ions; and basic if it contains a lesser concentration of hydronium ions than hydroxide ions.,
