Acids and Bases Michael O.

What are acids An acid is a substance that releases hydrogen ion when dissolved in water Things like vinegar or lemons are sour because they contain acids

Properties of Acids Acids are sour Acids conduct electricity Acids can corrode things Acids react with certain chemicals that cause color change.

What is base A base is a substance that releases hydroxyl ions when dissolves in water Todays soaps are made from fat and oils and a chemical compound called a base.

Properties of a Base Bases taste bitter. Bases feel slippery Like acids, bases conduct electricity. Like acids, bases can corrode things. Bases also like acids, react with certain chemicals that cause color change.

What Are Indicators An indicator is a chemical that when in an acid or base it changes color. Some examples of indicators are grape juice, Hydrangeas, red cabbage, beets, and cherries.

What is a Ph scale The ph scale measures the concentration of hydrogen ions in a solution. The Ph scale ranges from 1 to 14, where 1 threw 7 means it an acid and 7 to 14 means it’s an base. Neutral is 7 on the Ph scale,. Neutral means neither acid or base.

What is neutralization Neutralization is when an acid and a base react to produce salt and water. Salt is sodium chloride which is a substance produced when a acid reacts with a base.

What is an electrolyte An electrolyte is an substance that conducts an electric current when it is dissolved in water. Pure distilled water is not a good conductor of electricity.

What is a nonelectrolyte A nonelectrolyte is a substance that doesn’t conduct an electric current when dissolved in water. An example of a nonelectrolyte is sugar.

What is ionization Ionization is the formation of ion.
