HELP

Predict whether the following double-replacement reaction will produce a precipitate: AgNO3 + KOH KNO3 + AgOH.


No; all products are soluble

Yes; the KNO3 will precipitate

Yes; the AgOH will precipitate

Yes; both the KNO3 and AgOH will precipitate

Answer 1

Answer: The correct answer is yes; the AgOH will precipitate.

Step-by-step explanation:

Double-displacement reactions are defined as the reactions in which exchange of ions takes place. The chemical equation representing this reaction follows:

`AB+CD\rightarrow AD+CB`

For the given chemical equation:

`AgNO_3(aq.)+KOH(aq.)\rightarrow KNO_3(aq.)+AgOH(s)`

By Stoichiometry of the reaction:

1 mole of silver nitrate reacts with 1 mole of potassium hydroxide to produce 1 mole of potassium nitrate and 1 mole of brown colored solid named as silver hydroxide.

Hence, the correct answer is yes; the AgOH will precipitate.

Answer 2

The correct answer among the choice listed is the third option. The reaction between silver nitrate and potassium hydroxide will yield a precipitate which is the silver hydroxide product. This is because this substance is not very soluble in aqueous solution.
