Suppose 1.43 g of barium nitrate is dissolved in 150. mL of a 49.0 mM aqueous solution of sodium chromate. Calculate the final molarity of barium cation in the solution.

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.

catya your not at all which answer i've seen you do this on another question!
