A20.0 ml sample of 0.150 m ethylamine is titrated with 0.0981 m hcl. part a what is the ph after the addition of 5.0 ml of hcl? for ethylamine, pkb= 3.25. what is the ph after the addition of 5.0 of ? for ethylamine, = 3.25. 10.04 11.79 11.46 9.71

elements make up everything, and they combine to make compounds.

the answer is c

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.
