Why oxalic acid is heated before titration with KMnO4?
Oxalic acid is generally warmed slightly because it is not completely soluble and heat helps this. It aids in accuracy of the titration.
Is citric acid powder the same as energy?
No. Citric acid is matter. Energy is that which allows change in matter in the form of heat and movement.
What is the chemical equation for the reaction of citric acid and sodium hydroxide?
C6H8O7 + 3NaOH --> Na3C6H5O7 + 3H2O + HEAT ---------------------------------------------------------------------------------------------------- C3H5O(COOH)3(aq) + 3NaOH (aq) --> Na3C3H5O(COO)3(aq) +3H2O(l) +heat citric acid + sodium hydroxide --> Trisodium citrate +water +heat
Why do we heat KSCN Fe solution befor titration with EDTA?
We usually heat KSCN Fe solution before titration with EDTA so as to produce crystalline crust forms.
Why you heat oxalic acid and sulphuric acid solution?
During redox titration oxalic acid is a covalent compound and can not accept oxygen easily from an oxidizing agent so heat is necessary to break down the covalent bonding.

Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
Can citric acid be separated from water?
Yes - evaporate the water off with heat.

Can citric acid be used as a seasoning?
What's happening is that the citric acid denatures some proteins. Heat also denatures proteins, so it's similar to cooking, but since no (or, at least, very very little) heat is involved, it's not exactly the same (it won't necessarily kill parasites or bacteria, for example, and only those portions that the citric acid penetrates to will be affected at all).
Why there is a need to warm the solution of sulfuric acid and oxalic acid during redox titration?
Adding heat to a reaction usually speeds up a reaction.

During redox titration oxalic acid is a covalent compound and can not accept oxygen easily from an oxidizing agent so heat is necessary to break down the covalent bonding.
What are the identification tests for citric acid?
make a solution of compound,add NH4Oh to it,boil,,,,till we cant smell it ..now add CaCl2solution. No ppt. ,heat for 2 minutes...appearance of white ppt. confirms citric acid.....the white ppt. is of calcium citrate.
Is baking soda and citric acid a endothermic or exothermic reaction?
It is endothermic. The heat of the water in the calorimeter decreases (giving you a -deltaH), which means that the system absorbed heat, making the reaction endothermic.
Is citric acid sodium hydrogen carbonate endothermic or exothermic reaction?
im guessing here but it is probaly exothermic reaction as there is alot of heat given of
