30.00 ml of a h2so4 solution with an unknown concentration was titrated to a phenolphthalein endpoint with 44.45 ml of a 0.1489
kodGreya [7K]

The concentration of the H2SO4 solution should be 0.1101 M.

Calculation of the concentration:

Since

Volume of H2SO4 = 30.00 mL = 0.030 L

Volume of NaOH= 44.45 mL = 0.04445 L

Concentration of NaOH= 0.1489 M

Now

The balanced equation is

H2SO4 + 2NaOH → Na2SO4 + 2H2O

Now the concentration of the H2SO4 solution is

b*Ca*Va = a*Cb*Vb

here,  b = the coefficient of NaOH = 2

Ca = ?

Va = the volume of H2SO4= 30.0 mL = 0.030 L

a = the coefficient of H2SO4 = 1

Cb = the concentration of NaOH = 0.1489 M

Vb = the volume of NaOH = 44.45 mL = 0.04445 L

Now

2*Ca*0.030 = 1* 0.1489* 0.04445

0.060 * Ca = 0.00661

Ca = 0.1101 M

Hence, The concentration of the H2SO4 solution is 0.1101 M.

In the lab, you added an excess of acetic acid to drive the reaction forward, favoring products at equilibrium according to Le C
AysviL [449]

Answer:

Remove exess water

Explanation:

The reaction involved is an esterification reaction. Esterification is a reaction in which alcohol and carboxylic acid reacts to yield an ester and water. It is analogous to the inorganic neutralization reaction.

According to Le Chatelier's principle , one method of driving the equilibrium towards the forward reaction is by removal of one of the products. In this case, if water is removed, the forward reaction is favoured.
