Answer:
3) ester
Explanation:
Esterification is the process in which alkanol and alkanoic acids reacts in the presence of a catalyst and heat. The product is usually an ester(alkanoate) and water.
For the reaction between ethanoic acid and 1-butanol, the product is butylethanoate and water as shown below:
CH₃COOH + C₄H₈OH → CH₃COOC₄H₈ + H₂O
D.) He arranged elements by Atomic Masses
Answer:
<u> </u><u>85.952 ml</u>
needed to titrate the excess complexing reagent .
Explanation:
Lets calculate
After addition of 80 ml of EDTA the solution becomes = 20 + 70 = 90 ml
As the number of moles of
=
=
=0.01172
Molarity = 
=
=0.000586 moles
Excess of EDTA = concentration of EDTA - concentration of CoSO4
= 0.009005 - 0.000586
= 0.008419 M
As M1V1 ( Excess of EDTA ) = M2V2 


V2 =85.952 ml
Therefore , <u>85.952 ml </u>
needed to titrate the excess complexing reagent .
