Ascientist dissolves 5 g of potassium chloride (kcl) crystals in a bottle of water until the final volume is 100ml.
what the correct way to label the concentration of the potassium chloride solution described in the scenario?
a. 5% (v/v) kcl
b. 5 ppm kcl
c. 5% (m/m) kcl
d. 5% (m/v) kcl

explanation:

i think option no d is the correct answer

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.
