When a weak acid and a strong base are mixed, the resulting ph will be 7/7/7 (circle the correct answer). 10. for lewis acids and bases, the base is defined as an electron pair donor/acceptor (circle the correct answer). 11. when comparing anions from the same period, higher electronegativity of a in the ha bond increases / decreases (circle the correct answer) aoid strength 12. when comparing anions from the same group, larger size of a in the h-a bond increases / decreases (circle the correct answer) acid strength 13. a 0.10 m solution of a weak monoprotio acid has a hydronium-ion concentration of 4.8 x 10 "m. what is the acid-ionization constant, ka, for this acid? pk.? 14. if the resulting ph is 7, it was most likely a titration a. strong acid, strong base b. strong acid, weak base c. weak acid, strong base d. weak acid, weak base 15. a strong acid, weak base titration would result in a ph of 7 (circle the correct answer). 16. a buffer can neutralize acid because: a. the weak acid grabs h' b. the conjugate base grabs h c. the buffer ph cannot be changed by any amount of acid d. water grabs h and becomes neutral 17. calculate the ph of a solution that is 2.00 mhf, 1.00 m naoh, and 0.472 m naf. (ka - 7.2 x 10-4 18. qualitative analysis does not: a. characterize all ions in one step
