Answer:
Double Displacement (Metathesis)
Explanation:a chemical reaction between two compounds in which parts of each are interchanged to form two new compounds (AB+CD=AD+CB)
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.
