Chemistry Help! What is the balanced equation of vinegar(acetic acid) + NaOH

[From: ] [author: ] [Date: 11-05-14] [Hit: ]
So percentage composition = 60x/5.Phenolphthalein is used as an indicator and its presence in the titration is said to be negligible when it comes to the reaction.-The net ionic equation is [H+] + [OH-] ---> H2O, [Na+] and [CH3COO-] are spectator ions.......
We did a acid-base titration lab where we added NaOH to a vinegar mixture with phenolphthalein. Not even sure I got the reactant part right xD! thanks in advance!

Balanced equation:
CH3COOH + NaOH = H2O + NaCH3COO

NaCH3COO is sodium acetate

Further to your subsequent query,

You have the number of moles of NaOH.

No. of moles of NaOH = No. of moles of Acetic Acid = x

Acetic Acid has a Mr of (12+3+12+16+16+1 = 60gmol-1)

Mass of acetic acid = x*60 = 60x

So percentage composition = 60x/5.12g x 100% = Ans

OH- + HC2H3O2 --> H2O + C2H3O2-

Phenolphthalein is used as an indicator and its presence in the titration is said to be negligible when it comes to the reaction.

The net ionic equation is [H+] + [OH-] ---> H2O, [Na+] and [CH3COO-] are spectator ions.
