In the double replacement reaction between na2so4 (aq) and bacl2 (aq), will a precipitate form?

no. this reaction produces no insoluble products.

yes. the nacl will precipitate.

yes. the baso4 will precipitate.

yes. both the nacl and the baso4 will precipitate.

The correct answer is Yes, will precipitate.

Explanation:

Double displacement reaction is defined as the reaction in which exchange of ions takes place.

Precipitate is defined as the insoluble salt which emerges when two different solutions are mixed together. It settles down at the bottom of the flask after some time.

The chemical equation for the reaction of sodium sulfate and barium chloride follows:

Barium sulfate settles down in the reaction flask and is considered as a precipitate.

Hence, the correct answer is Yes, will precipitate.

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.
