Answer:
A i am pretty sure if not let me know and i will fix it.
Explanation:
Answer:
It is a strong acid.
Explanation:
A strong acid is any acid that is completely ionized in solutions to release the greatest number of hydronium ions or protons when placed in a solution.
So, when 99.9% of a substance dissociates to release hydronium ions. It is considered as a strong acid.
Ethanol is polar because the oxygen atoms attract electrons because of their higher electronegativity than other atoms in the molecule. Thus the -OH group in ethanol has a slight negative charge. Ammonia (NH3) is polar. Sulfur dioxide (SO2) is polar.
Answer:
Two characteristics that make water a good choice for the recrystallization solvent for benzoic acid are
- Low solubility for benzoic acid at room temperature
- Less expensive
Explanation:
Characteristics of a Good Recrystallization Solvent:
- Cheap.
- High volatility.
- No reaction with substrate to be made pure.
- Insoluble impurities should not be dissolced by the olvent at all temperatures.
- At room temperature the solvent should have high solubility for soluble impurities well
- At room temperature the substance to be purified should be insoluble in the solvent.
As such water has both low solubility for benzoic acid at room temperature and water is cheap or readily available
D bc they actually contacted each other
