Why Oxalic acid is stonger than malonic acid?

A strong acid has a stabilized conjugate base. Oxalic acid is stronger than malonic acid because its conjugate base has much more resonance structures than malonic acid's conjugate base.


What carboxylic acid would decarboxylate by heating?

A classic example of a carboxylic acid decarboxylation occurs in the malonic ester synthesis. The malonic ester synthesis is a chemical reaction where diethyl malonate or another ester of malonic acid is alkylated at the carbon alpha (directly adjacent) to both carbonyl groups, and then converted to a substituted acetic acid. Malonic acid is another example of an acid that will decarboxylate when heated (not sure at what temperature this happens, though)The structure of malonic acid is HOOC-CH2-COOH.


What is Malonic acids role with respect to succinate dehydrogenase?

Malonic acid is a competitive inhibitor of succinate dehydrogenase.


Is malonic acid a diprotic acid?

Yes, it is diprotic, HOOC-CH2-COOH


When malonic acid is heated with P2O5 what is formed?

Carbon Suboxide


A solution of malonic acid h2c3h2o4 was standardized by titration with 0.1000 M Naoh solution if 20.76 ml of the naoh solution were required to neutralize completely 13.15 ml of malonic acid solution?

.0899M


How many protons can be lost by acetic acid HC2H3O2?

Malonic acid has pKa values of 2.83 (pK1) and 5.69 (pK2). If malonic esters are used then on treatment with a strong base like sodium ethoxide, the methylene (-CH2-) hydrogen can be deprotonated, but I am not sure if that is possible for malonic acid as that will lead to a tri-anion.


Is Malonic Acid polar?

Yes it is because of it's 2 ends of hydroxide which is polar.


Is the apple a acid or a base?

Yes, several weak acids in it. pH is about 3.5 to 4.5. There is even an acid named by them: malonic acid (propane-di-oic acid, C3H4O4).


What reaction gives caffeine?

Caffeine can be synthesised (made artificially in a lab) by reacting dimethylurea with malonic acid.


In the Briggs Rauscher reaction can the Malonic acid be replaced by Oxalic acid?

In theory, any organic molecule with an enolic hydrogen (as in carboxylic acids, e.t.c.) can be used, it has simply been found that the malonic acid gives the most easily discernable colour changes and is just generally better for the reaction (Sorry for my lapse in scientific language there, I'm tired!). So the answer, in basics, is yes


What is the purpose of a titration experiment?

To deduce the concentration of a unknown solution from a known solution. Acid/base titration are common.
