Across
  1. 1. a scale from 0 to 14 that is a measure of the hydrogen and hydroxide ion concentrations, how strong or weak an acid or base is.
  2. 7. a chemical compound that dissociates into hydroxide ion(s) and a positively charged ion when mixed with water
  3. 8. not able to be dissolved by a particular solvent. Some things can be dissolved by water and some cannot (insoluble)
  4. 9. forms when a solvent is saturated and more solute is added. The extra solute ‘precipitates’ to the bottom
  5. 10. a chemical compound that is produced in a chemical reaction (what you have at the end of the reaction)
  6. 11. the ratio of the amount of solute to the volume of solvent
  7. 14. the substance that changes state when a solution is prepared or is present in the smallest amount
  8. 15. when a reactant is converted to a product
  9. 17. matter cannot be created nor destroyed
  10. 18. when a solvent is ‘full’ of solute and cannot dissolve any more
  11. 19. When an acid is mixed with water, it dissociates into a negatively charged ion and a hydrogen ion, H+
Down
  1. 2. When a base is mixed with water, it dissociates into a positively charged ion and a hydroxide ion, OH-.
  2. 3. able to be dissolved by a particular solvent
  3. 4. a chemical compound that is consumed in a chemical reaction (what you start with)
  4. 5. Describes a chemical reaction by indicating the formulas of all reactants and products
  5. 6. when a reactant is not converted to a product
  6. 12. a chemical compound that has a hydrogen ion(s) (also called hydronium ions) when mixed with water (H+)
  7. 13. a chemical compound that has a negative or a positive charge
  8. 15. occurs when chemical reactants are converted into chemical products
  9. 16. a description of a chemical compound using the letter designations of the elements
