<u>Answer:</u> The chemical reaction is given below.
<u>Explanation:</u>
Double displacement reactions are defined as the reactions in which exchange of ions takes place. The general equation for this reaction follows:
The chemical equation for the reaction of phosphoric acid and potassium hydroxide follows:
By stoichiometry of the reaction:
1 mole of phosphoric acid reacts with 3 moles of potassium hydroxide to produce 1 mole of potassium phosphate and 3 moles of water.
This is also known as neutralization reaction.
In a periodic table, a set of properties repeats from Row to row. I guessed it because both B and C have same meaning and A is not correct. So, the answer is D.
No Ag cannot react with NaOH because Ag is less reactive than Na in the reactivity series and can't displace it
