Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
And I don't see any of the particles. so I can only answer the first one.
Resultant aqueous solution of a hydrogen oxalate salt is basic in nature.
<h3>What is pH?</h3>
pH scale is used to determine the acidity, basicity or neutral nature of any solution.
- Values from 0 to 6.9 shows the acidity.
- 7 shows the neutrality.
- And 7.1 to 14 shows the basicity.
Chemical equation for the given salt in an aqueous solution will be shown as:
NaHC₂O₄ + H₂O → NaOH + H₂C₂O₄
From the equation it is clear that reaction produces-
- NaOH which is a strong base and
- H₂C₂O₄ oxalic acid which is a weak acid.
So that resultant solution is basic in nature.
Hence the aqueous solution of salt is basic.

It seems that you have missed the necessary options for this answer, but anyway, the answer for this would be H20. The specie that is a conjugate acid of OH- is H20. H20 is the conjugate acid and OH- is the conjugate base. Hope this answers your question. Have a great day!
