What is the molarity of a potassium chloride solution that has a volume of
400.0 ml and contains 85.00 grams
KCI?
What mass of KBr is present in 25 ml of
a 0.85 M solution of potassium chloride?

i think it is d. e because the next one is igneous.

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.

a corroding iron, if that's one of your choices
