Across 6. an acid that only slightly dissociates in an aqueous solution 9. acid with one acidic proton 10. Acids produce hydrogen ions in aqueous solutions, while bases produce hydroxide ions 11. remains of an acid molecule after a proton is lost 14. It can behave either as an acid or a base 17. the transfer of a proton from one molecule o another of same substance 19. acid is an electron-pair acceptor; base is an electron-pair donor 21. a base that reacts with water to produce hydroxide ions to slight extent in an aqueous solution 23. completely dissociates to produce an H+ ion and the conjugate base 27. ionic compound 30. formed when a proton is added to a base 31. a convenient way to represent solution acidity 32. It is a strong acid in its first step, but a weak acid in its second step. 33. acid that has two acidic protons 34. a statement that expresses generally observed behavior

Down 1. The independent pressure exterted by different gases in a mixture. 2. acidic proton is attached to an oxygen atom 3. (amount dissociated/initial concentration in a solution) x 100% 4. measures the strength of an acid in a solution, Ka 5. another name for Calcium Hydroxide 7. a hydrated proton 8. an acid is a proton donor, and a base is a proton acceptor 12. interaction between solute particles and water molecules 13. change in energy that takes place when seperated gaseous ions are packed together to form an ionic solid 15. simplest whole number ratio of atoms in a compound 16. concept that energy can only occur in discrete units called quanta 18. Acid with more than one acidic proton. They dissociate in a stepwise manner with only one proton at a time. 20. They have identical atomic numbers, but different mass numbers. 22. energy due to motion of an object 23. metal hydroxide salt that completely dissociates its ions in water 24. PV=nRT 25. process depends on volatility of the components 26. eight electrons are required to fill orbitals 28. a technique in which onw solution is used to analyze another 29. bond of two or more atoms of the same or different elements
