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.
The student may also need to know about glass beads of water. The density of glass beads is an important number and they can be measured using the density measurement scale. The answers for both of these questions will help them find the solutions that they need.
The answers for the question, “What about acid additions,” are also a good way to learn about the human body. Both potassium and sodium are found in foods and different salts and electrolytes are added to them to make them easier to digest. These two terms will help students learn how to measure the volume of their own bodies, and they will also be able to find the answers to other problems that they will encounter.
