It is true/falseit that when hydrogen cyanide, h c n , dissolves in water, the solution is weakly conducting and acidic in nature. this is because hydrogen cyanide, h c n is a blank that blank support the movement of charge. in addition, since specifically blank formed, the solution is blank. it is blank that when acetone, ch3coch3, is dissolved in water conducting solution results. this is because acetone, ch3coch3 is a blank that blank support the movement of charge the words are: true, false, weak electrolyte, strong electrolyte, non-electrolyte, does not, does, h+ is, oh- is, no ions are, acidic, basic, neutral.

Part b: study of equilibrium on solubility: mg(oh)2(s) ⇌ mg2+(aq) + 2 oh–(aq) cloudy clear (pink) 7. a. b. 8. a. b. 9. 10. 11. 12. when adding concentrated hydrochloric acid, how did the appearance of the equilibrium mixture change? the change in appearance indicated a shift in the point of equilibrium. in which direction did the equilibrium shift? (l) left (r) right explain your answer to question 7a. you should indicate which ion was added to or removed from the equilibrium mixture. when adding edta, how did the appearance of the equilibrium mixture change? the change in appearance indicated a shift in the point of equilibrium. in which direction did the equilibrium shift? (l) left (r) right explain your answer to question 8a. you should indicate which ion was added to or removed from the equilibrium mixture. upon heating in which direction is the equilibrium shifting? upon cooling in which direction is the equilibrium shifting? is the forward reaction a. endothermic explain your answers to questions 9, 10, and 11.
