Across
- 5. An example of a physical change and is a solution as well (HINT: This was the solvent and solute in another answer!)
- 7. The substance that is doing the dissolving
- 8. This is the solute and it is used in a solution to make rock candy
- 10. water is commonly known as this because it can dissolve almost anything and act as both an acid and as a base
- 11. this determines if something is acidic, basic, or neutral. Acidic is red, basic is blue, and neutral doesn't change the color
- 14. this is a property of some bases and it is difficult to hold firmly. EX. Ice and soap
- 16. The substance that is being dissolved
- 20. this is an acid, an aqueous solution, and many people think it smells and tastes bad
- 21. this has a pH from 1-6 and it releases hydronium ions (OH-)
- 22. this is used as agricultural fertilizer and it is an example of a base
- 23. This helps the solute in a solvent dissolve faster (This is the independent variable in an experiment)
- 24. this is a property of some bases and it has a sharp or bad taste or smell. EX. Soap
- 26. it can harm the environment by too much exposure to humans and the environment.
- 29. this is determined by a scale and it is the amount of matter in an object
- 31. Can’t be reversed and a new substance is formed.
Down
- 1. The measurement of thermal energy within an object and is one of three factors that affects the rate of solubility
- 2. this is a very powerful base and it is a cleaning product. This can seriously hurt your skin as well.
- 3. this has a pH from 8-14 and it releases hydroxide ions (H+)
- 4. Can be reversed and doesn’t change what a substance is
- 6. this is a property of some acids and it can chemically destroy exposed body tissues
- 9. This is an example of a chemical change and it usually occurs when metal is exposed to moisture and it is then left out for long periods of time
- 12. A mixture of two or more substances that is the same throughout
- 13. many acids have this taste. Ex. Lemon and Vinegar
- 15. this contains a natural pH indicator that changes color depending on the acidity of a solution
- 16. a solvent that has as much solute in it as it can dissolve
- 17. when there is more solute in a solvent than can be dissolved
- 18. this is an acid, a fruit, and there is a large debate on whether this or the color came first
- 19. this tells the pH of some substances by changing the color of the strip. Red means acidic and blue means basic.
- 25. this is an example of a base and it is used to clean other things or yourself
- 27. Something to determine whether something is an acid, a base, or neutral on a scale of 0-14
- 28. this is an acid, a fruit, it has seeds, and it is commonly used in cooking
- 30. This is the solvent and it can act as both an acid and a base
