Question

For the reaction of acetic acid, CH_3COOH, with sodium hydroxide, NaOH, write the complete, balanced equation. Label the acid and its conjugate base. write the net ionic equation. how many acid protons are there in a molecule of acetic acid? What does an acid-base titration accomplish? What is an indicator and how does it function in a titration experiment? By using the proper units for volume and concentration in the titration equation, show that Moles_acid = Moles_base What is the molarity of an unknown arid if 40.5 mL of the acid can be titrated to an end point by 20.5 mL of 0.2250 M NaOH? Show your work and be careful with significant figures.

Explanation / Answer

1)

CH3COOH + NaOH   -----------------> CH3COONa + H2O

(acid)                                                    (conjugate base)

CH3COOH - acid

CH3COONa - conjugate base.

b)

net ionic equation :

H+ (aq) + OH- (aq) ------------> H2O (l)

c)

there are only one acid proton in acetic acid.

CH3COOH -----------> CH3COO- + H+

only one H+ that is one proton.

2)

this acid base titration gives buffer.
