Which anion evolves a gas with a fruity odor when treated with concentrated sulfuric acid and ethanol?
- A.
BrO3
- B.
CH3COO
- C.
ClO4
- D.
SO4
Correct Answer
B. CH3COOExplanation
The anion CH3COO (acetate) releases a gas with a fruity odor when it is treated with concentrated sulfuric acid and ethanol. This reaction involves the formation of ethyl acetate, which is an ester commonly used in solvents and has a distinctive sweet, fruity smell similar to pears. The process is a classic example of esterification, where an acid (from the acetate ion) reacts with an alcohol (ethanol) in the presence of an acid catalyst (sulfuric acid) to form an ester and water. This reaction is not only important in chemical synthesis but is also used in flavorings and fragrances.Rate this question:

Increases osmotic load of the GIT:
- A.
Bulk-forming laxative
- B.
Emollient laxative
- C.
Saline cathartic
- D.
Stimulant laxative
Correct Answer
C. Saline catharticExplanation
Saline cathartics are substances that increase the osmotic load of the gastrointestinal tract (GIT). When taken orally, they draw water into the intestines through osmosis, which softens the stool and promotes bowel movements. This increased osmotic load stimulates the movement of fluid into the intestines, resulting in increased water content in the stool and ultimately relieving constipation. Therefore, saline cathartics are the correct answer as they directly increase the osmotic load of the GIT.Rate this question:

The following can cause a shift of equilibrium except:
- A.
Catalyst
- B.
Concentration
- C.
Pressure
- D.
Temperature
Correct Answer
A. CatalystExplanation
A catalyst is not capable of causing a shift of equilibrium because it does not affect the position of the equilibrium. Instead, a catalyst speeds up the rate of the forward and reverse reactions equally, allowing the system to reach equilibrium faster but not altering the equilibrium concentrations of reactants and products. In contrast, changes in concentration, pressure, and temperature can affect the equilibrium position by altering the relative concentrations of reactants and products.Rate this question:

What characteristic color does copper impart to a nonluminous flame?
- A.
Blue
- B.
Scarlet
- C.
Green
- D.
Emerald
Correct Answer
C. GreenExplanation
Copper, when exposed to a nonluminous flame, typically imparts a green color. This characteristic green flame test is a common method used in qualitative chemical analysis to identify the presence of copper ions in a compound. When copper heats up, it excites the electrons, which then release energy as they return to their original energy state. The energy released falls within the green portion of the visible light spectrum, hence producing the green flame. This distinct coloration is useful in laboratory settings for quickly indicating the presence of copper in a sample.Rate this question:
