We have 30% (w/w) HCl this means :
100 g solution contains 30 g HCl
?? g solution contains 7.5 g HCl
By cross multiplication:
Mass of solution =
= 25 g solution
Answer is: <span>No, because she did not stop adding base once the color changed.
</span>The endpoint<span> is the point at which the indicator changes colour in a colourimetric </span>titration and that is point when titration must stop or results are going to be wrong, because t<span>he </span><span>equivalence point of titration is not measured right.</span>
Natural polymer is more similar chemically to biopolymers.
Polymers are large molecules or high-molecular weight compounds formed from small repeating units. These repeating units are called monomer. Polymers are synthesized naturally and artificially. The number of repeating units in a chain is called the degree of polymerization.
There are two types of polymers:
1. Natural Polymers
2. Synthetic Polymers
Biopolymers are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules.
Synthetic polymers are the human-made polymers sometimes referred as plastics. The two major types of synthetic polymers are addition polymers and condensation polymers.
What are biopolymers?
Biopolymers polymer materials that form in living organisms. There are three main biopolymers in living systems; polysaccharides, proteins and polynucleotides (nucleic acids). The structural unit of polysaccharides is monosaccharides (sugars). When two monosaccharides join together to form a glycosidic bond, it releases a water molecule. Therefore, polysaccharides are condensation polymers. Polysaccharides play structural and functional roles in organisms. Glycogen is a storage polysaccharide, whereas cellulose is a component in the cell walls of plant cells. Glucose is the monomer for both glycogen and cellulose polymers.
Hence, we have conclude Biopolymers are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules.
