Acid / Base Worksheet

Answer the questions to the Acid/Base worksheet by

clicking through the following slides that were made by you

and your classmates.

Acid

Acid- substances produced by hydrogen ions. Comes from Latin word acidius which means “sour”

base

• A substance that produces hydroxide ions in solution or accepts hydrogen ions

• Bases taste bitter• Bases feel slippery• Strong bases are very dangerous and can

burn your skin

Reactions

• When acids and bases are added to each other they react to neutralize each other if an equal number of hydrogen and hydroxide ions are present.

• HCl + NaOHNaCl + H2O• The scientific name for the reaction is

called neutralization.

Measurment

•You measure the strength by finding the PH level.

Acid rain is a result of chemicals or pollution in the air being taken to the clouds and atmosphere with the rain that is evaporated from the earth.

Acid rain is very harmful to the environment. They also damage more than just the environment-they can damage our health. High levels of SO2 in the air aggravate various lung problems in people with asthma and can cause breathing difficulties in children and the elderly. (Normal rainwater has a pH of 5.6. When the pH level of rainwater goes below 5.6, it is considered acid rain.)

High environmental acidity exists in most of Europe, parts of Canada, and developing countries like China and India. Because the better known form is any precipitation that contains high amounts of sulfur dioxide and nitrogen oxide that occur because of air pollutants.

We can help to reduce acid rain by conserving energy and promoting conservation and renewable energy efficiency in our community.
