No, the product is water sensitive. The Anhydride will decompose if in contact with water. Sulfuric acid will any way convert the phosphate to phosphoric acid.
You can only make it in absense of water.
Of course if you cannot buy the chlorinated Acyl ,then you have to do the chlorination first.

Re: Esterification Reaction
You can not use aqueous solution. SOCl2 either CH3COCl will decompose in presence of water.
Why to produce acetylchloride from acetic acid and thionylchloride, from cost side buy directly acetylchloride and add it to the dry phosphate.

Re: Esterification Reaction
The stoechometric mixture of the reactants guid to it. Probably take more of the phosphate. Anhydride means remove water. The anhydride can made by 2 CH3COOH => (CH3CO)2O + H2O but also with different acids. CH3COOH + C2H5COOH => CH3CO(C2H5CO)O + H2O H3PO4 + CH3COOH => CH3COH2PO4 + H2O

Re: Esterification Reaction
First it's not a ester. Ester made from acid and alcohol.
What you talking about is a mixed acid anhydride.
To get this take acetylchloride CH3COCl and disodium hydrogen phosphate Na2HPO4.
CH3COCl + Na2HPO4 => CH3CONaHPO4 + NaCl

Re: I read somewhere online that the compounds that appear blue have more conjugation than red compounds. Why is that?
The appearance of a colour of something is the opposit colour of the light what will be absorbed. Blue colour means red to yellow light will be absorbed and vise versa. So blue colour has more conjugation for this reason and vise versa.

Re: Balanced equation for the reaction
Silver chloride and lead chloride will not react each other, because both have bad soloubility.
You can do the same as described with the silver nitrate, add Sodium chloride to lead nitrate then lead chloride will precipitate.

Nitrite Hydrate is negative charged. H2NO3- You wrote a neutral molecule H2NO3. The neutral molecule is not existing. As described in your link it is a compound with nitrite NO2- and water H2O. You need also a positiv charge like sodium. So you would have NaNO2 with one water attached. This is total...

Re: How to calculate the molarity of glacial acetic acid?
Its correct so far.
Only
100 g correspond to 95,3 ml is correct.
Only
is strange, what is 1001.049?Volume of 100 grams of glacial acetic acid = 1001.049 = 95.329 ml
100 g correspond to 95,3 ml is correct.

Re: Hi! Please help me with this.
First write the acids in half structure form
What means
C9H19COOH and C3H7COOH
Acids react with metal under developing hydrogen
2 RH + 2 Li => 2 RL + H2 and
2 RH + Ca => R2Ca + H2
Combine it with the given acids.

That what it means , there is no H2NO3 in this world, because nitrogen is only pentavalent.

Re: Help me balancing this equation! Grade 10
H2NO3 is not existing . Nitrogen is not hexavalent. It's only HNO2 or HNO3 existing.
NO2 dissolved in water gives
H2O + 2 NO2 => HNO3 + HNO2

H2O + 2 NO2 => HNO3 + HNO2

It is not generally wrong. What do you get if you solve my proposal? Compare the two results. In the given files they using H+ and OH- together for solving the equation. This is mathematicaly possible but not in reality. H+ can not exist with OH-. This will be water. At the end they get acetic acid ...
