Across
  1. 4. A compound that changes color at a specific pH value and is used to determine the pH of a solution.
  2. 9. A substance that increases the concentration of hydrogen ions (H+) in a solution, typically having a sour taste.
  3. 10. Common table salt, an ionic compound consisting of sodium and chloride ions.
  4. 12. (Acetic Acid) A weak acid solution composed mainly of acetic acid and water, used in cooking and as a preservative.
  5. 15. The ion that forms when a hydrogen ion (proton) bonds with a water molecule, typically present in acidic solutions.
  6. 17. A strong acid commonly used in industrial processes and as a laboratory reagent.
  7. 18. A substance that increases the concentration of hydroxide ions (OH-) in a solution, often characterized by a bitter taste and slippery feel.
  8. 19. A chemical indicator that turns pink in basic solutions and is colorless in acidic solutions.
  9. 20. A chemical compound used as a disinfectant and bleach, made from calcium hypochlorite.
Down
  1. 1. A solution that resists changes in pH when small quantities of an acid or a base are added.
  2. 2. A technique in laboratory chemistry used to determine the concentration of an identified analyte.
  3. 3. An ionic compound that results from the neutralization reaction between an acid and a base.
  4. 5. A strong base commonly used in soap making and as a drain cleaner.
  5. 6. A blended indicator that changes colors across a wide range of pH levels to indicate the strength of an acid or base.
  6. 7. (Sodium Bicarbonate) A mild base used in baking to react with acids and release carbon dioxide, causing dough to rise.
  7. 8. A negatively charged ion that makes solutions basic when it increases in concentration.
  8. 11. An indicator that turns red in acidic environments and yellow in basic environments.
  9. 13. A chemical reaction in which an acid and a base react to form water and a salt, effectively canceling each other's effects.
  10. 14. A dye extracted from lichens that changes color with pH changes; red in acidic solutions and blue in basic solutions.
  11. 16. A numerical scale used to specify the acidity or basicity of an aqueous solution; values below 7 are acidic, above 7 are basic, and 7 is neutral.
