Why must the polymerization step have a basic solution?

Chemistry

5 0

The polymerization solution must be basic in order for the diamine is not protonated and is nucleophilic. If the solution is not basic, it will not be enough for the nucleophilic amine to react with the acid chloride and form polymer product. This will result to a lowered product yield.

50.0 mL of 0.500 M HCN and 25.0 mL of 0.500 M sodium hydroxide combination can be used to make a buffer with a pH of 4.2. The KK

an of benzoic acid, C6H5COOH, is 6.5×10-5 and the an of hydrocyanic acid, HCN, is 4.9×10-10.

Benzoic acid

A white (or colourless) solid with the chemical formula C6H5CO2H, benzoic acid is pronounced: "bnzo.k." The simplest aromatic carboxylic acid is this one. The term comes from gum benzoin, which was the substance's exclusive source for a very long period. Many plants naturally contain benzoic acid, which is used as an intermediary in the formation of numerous secondary metabolites[9]. Benzoic acid salts are employed as food preservatives. An essential starting point for the industrial synthesis of many other chemical compounds is benzoic acid. The term "benzoates" refers to the salts and esters of benzoic acid.

When the temperature goes up, the pressure will go up.
lys-0071 [83]
Pressure is created by the number of collisions that occur between the molecules and the surface of container. If the temperature in the container is increased this will cause the molecules to move faster. ... By increasing the number of collisions, this will increase the pressure in the container.
Ex: A 5% increase in absolute temperature will resultin a 5% increase in the absolute pressure. ... Resultant pressure changes will vary. A useful thumb rule for water is that pressure in a water-solid system will increase about 100 psi for every 1 F increase in temperature.
