In an accident, a solution containing 2.5 kg of nitric acid was spilled. two kilograms of na2co3 was quickly spread on the area and co2 was released by the reaction by the reaction. was sufficient na2co3 used to neutralize all the acid?

First we must write a balanced chemical equation for this reaction

The mole ratio for the reaction between and is 1:2. This means 1 moles of will neutralize 2 moles . Now we find the moles of each reactant based on the mass and molar mass.

The was enough to neutralize the acid because 18.87:39.67 is the same as 1:2 mol ratio.

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.
