Chemistry
1 answer:
Trava [24]3 years ago
5 0

Answer:

D: When the acidity of a solution increases, the pH increases.

Explanation:

It is totally wrong to assert that when the acidity of a solution increases, the pH of the solution will increase

The right answer is that when the acidity of a solution increases, the pH value decreases.

  • The pH scale records the level of acidity and basicity of a substance.
  • It runs from 1 to 14
  • From 7 to 14 signifies increasing basicity
  • As the acidity of a substance increases, the pH value reduces.
  • For acids 1 is the highest acidity levels.

Select the true statements about eicosanoids. a. Eicosanoids are broken down within seconds to inactive residues. b. Arachidonic
Evgen [1.6K]

Answer: the true statements about eicosanoids includes options A,B,D,E

Explanation:

EICOSANOIDS are mostly produced from the precursor arachidonic acid, a C20 polyunsaturated fatty acid. They are broken down within seconds to inactive residues after synthesis.High concentrations of eicosanoids are necessary for effective action.The three major types of eicosanoids includes:

-prostaglandins,

- thromboxanes, and

- leukotrienes.

Depending on the above types mentioned, they play a role in inflammation, pain, fever promotion, blood pressure regulation, and blood clotting. They also influence the immune response and certain respiratory and reproductive processes.

However, eicosanoids are NOT transported in the blood stream to their site of action RATHER they exert their effects on the tissue where they are synthesized.

Consider the given examples listed here, find out which substance from the list will turn phenolphthalein pink? (a) vinegar ( b)
egoroff_w [7]

Answer:

(d) soap.

Explanation:

A soap is obtained by alkaline hydrolysis of a fat to yield the soap and glycerol. This process is known as saponification.

A soap solution is usually basic. Since phenolphthalein turns pink in an alkaline solution, then when phenolphthalein is added to a soap solution, the solution soon turns pink because it is alkaline in nature.

As a matter of fact, a soap sometimes has almost the pH of baking soda!
