Synthetic fiber or synthetic fibre (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). There are two types of polymerization: linear polymerization and cross-linked polymerization.

In a titration, acetic acid is used as the analyte and sodium hydroxide is the titrant. At the equivalence point, will the ph be

ValentinkaMS [17]

Titration involves acetic acid as the analyte and sodium hydroxide as the titrant. ph is more than 7 at the equivalency point.

The titration's equivalence point is the moment at which adequate titrant has been introduced to react to all of the material being titrated. A strong acid combined with something like a weak base produces a somewhat acidic salt. Similarly, combining a strong base with a mild acid yields a slightly basic salt.

When acetic acid combines with NaOH, it produces the salt sodium acetate and water. When acetic acid, CH3COOH, interacts with sodium hydroxide, sodium acetate, CH3COONa, and water are formed.

CH3COO- + H2O → CH3COOH + OH-

The acetate ion's reaction raises the ph to over 7.

Moles of acetic acid is equivalent to moles of sodium hydroxide at the equivalence point. As additional sodium hydroxide is added, the solution will become pink.
