Answer:
7.8 grams per cm
Explanation:
to get density you need the mass and volume then you divide them so
81.9 grams/10.5 cm gives 7.8g/cm
3 Neutralization reaction would be an acid and a base as reactants
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.
