Oxalic acid (h2c2o4) has a ka of 5. 9×10−2, while the hydrogen oxalate anion (hc2o−4) has a ka of 6. 1×10−5. Is an aqueous solution of a hydrogen oxalate salt (e. G. Nahc2o4) acidic, basic, or neutral?

Respuesta :

Resultant aqueous solution of a hydrogen oxalate salt is basic in nature.

What is pH?

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.
