Answer:
a) equivalence point
b) direct titration
c) primary standard
d) titrand
e) Back titration
f) back titration
g) standard solution
h) standard solution
I) indirect titration
j) end point
Explanation:
A volumetric analysis is one in which a solution of unknown concentration is determined from its volume. This is commonly referred to as titration.
In titration, a standard solution is reacted with another solution of unknown concentration. The point at which the concentration of the standard solution is equal to that of the analyte is known as the equivalence point (usually indicated by a colour change). An indicator may be added to the analyte solution to help identify when the reaction is complete.
<u>Answer:</u> The volume of the container needed is 554.6 L
<u>Explanation:</u>
To calculate the volume of the gas, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 3.0 atm
V = Volume of the gas = ? L
T = Temperature of the gas = ![25^oC=[25+273]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B25%2B273%5DK%3D298K)
R = Gas constant = 
n = number of moles of propane gas = 68.0 moles
Putting values in above equation, we get:
Hence, the volume of the container needed is 554.6 L
The answer is:
carboxylate
and protonated amines
The explanation:
when
The Carboxylic acids are polar . and the functional group carboxyl is formed from the hydroxyl and carbonyl group.
and about protonated amines:
-alkyl groups improve the basicity, aryl groups diminish it.
-Primary amides have an aromatic group or alkyl attached to an amino-carbonyl function.
- Primary amines are basic functions which could be protonated to the ammonium ion
