Answer: Water is polar and salts form ions in solution.

Explanation:

According to the concept of “Like dissolves like”, the polar solutes dissolve in polar solvents, and non-polar solutes dissolve in non-polar solvents.

Water being a polar solvent due to large electronegativity difference between hydrogen and oxygen is able to interact with the ions of the solute.

As water molecules are also polar in nature. So, oppositely charged ions interact with each other and dissolve in it.

Water can form hydrogen bonds with most of the substances and hence dissolve them . Thus water is considered as a universal solvent.

Aspirin can be prepared from salicylic acid ( C 7 H 6 O 3 CX7HX6OX3), which has a molar mass of 138.12 g/mol, and acetic anhydri
pychu [463]

Answer: The theoretical yield of aspirin is 4.14 g

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}  \text{Moles of salicylic acid}=\frac{3.20g}{138.12g/mol}=0.023moles

mass of acetic anhydride = density\times volume =1.082g/ml\times 3.71ml=4.01g

\text{Moles of acetic anhydride}=\frac{4.01g}{102.04g/mol}=0.039moles

C_9H_6O_3+C_4H_6O_3\rightarrow C_9H_8O_4+C_2H_3O_2  

According to stoichiometry :

1 mole of salycylic acid require 1 mole of acetic anhydride

Thus 0.023 moles of  salycylic acid require=\frac{1}{1}\times 0.023=0.023moles  of acetic anhydride

Thus salycylic acid is the limiting reagent as it limits the formation of product and acetic anhydride is the excess reagent.

As 1 mole of salycylic give = 1 mole of aspirin

Thus 0.023 moles of salycylic acid give =\frac{1}{1}\times 0.023=0.023moles  of aspirin

Mass of aspirin = moles\times {\text {Molar mass}}=0.023moles\times 180.15g/mol=4.14g

Thus theoretical yield of aspirin is 4.14 g
