Lactic acid (hc3h5o3) is a monoprotic acid with a ka value of 1.4 ✕ 10−4. (a) what volume of 0.15 m koh would need to be added to 25 ml of 0.086 m lactic acid to reach the equivalence point? (keep 2 significant figures) ml (b) at the equivalence point, would the aqueous solution be acidic, basic, or neutral? explain why. at the equivalence point, the solution will be . at this stage, all of the lactic acid in the solution will have reacted with the koh added, producing lactate ions (c3h5o3− ) and potassium ions (k + ) in the solution. the potassium ions will not affect the ph, but the lactate ions will make the solution .

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
