# Introduction to Acids and Bases Worksheet Answer Key

Understanding what the answer key is in an Introduction to Acids and Bases worksheet is essential. This answer key can be used when the students cannot figure out a question on their own, so that they can then go back and look for the answer. This worksheet has a question that asks you to write down the following words: “Fountain, water, crystal.”

Water, bicarbonate of soda, a chloride of sodium and bicarbonate of potash are known as “tables” of basic substances. Sodium is usually included in the formula because it is needed to make table salt. The problem with this worksheet is that it does not tell the students what the formulas are for sodium and what they can do with it, but that will come later in the lesson.

The next question asks students to give the whole numbers of the ratio of a cube to the square. This formula has been modified for the reason that students who have already learned the amount of a cube and how to multiply it by itself may not understand the calculation for the square. A cube is sometimes called a dodecahedron. Thus, a three sided dodecahedron is written in the three part series and this formula.

Crystal, which has two units, is another term that students will need to learn. This term is used for the correct sizes of things such as stones, jewelry, crystals and metal objects. The worksheet can be used to find the volume of a crystal or a bitumen.

Combining these two terms, there are some questions that ask students to list the volumes of liquids and the ratios of solids. Both these terms refer to a great number of things. The ratios of solids include the weights of the atoms that make up the solid and they also measure the volume of the solid.

Many students will need to know about the size of fluoride concentrations. Fluoride is used in drinking water, toothpaste and on foods. This is an important term that students should have a working knowledge of.
