Calculate the pH and pOH of 500.0 mL of a phosphate solution that is 0.285 M HPO42– and 0.285 M PO43–. (Ka for HPO42- = 4.2x10-1

jekas [21]

Answer: when concentrations of acid and base are same, pH = pKa

PH = 12.38 pOH = 1.62

Explanation: pKa= -log(Ka)= 12.38. PH + pOH = 14.00

What is the % yield of the reaction making 1.6 g of acetyl salicylic acid from 5.7 g of salicylic acid, 9.9 mL of acetic anhydri

artcher [175]

Answer:

Yield of reaction is 76.7%

Explanation:

The reaction of salicylic acid with acetic anhydride to produce acetyl salicylic acid is 1:1. That means 1 mole of salicylic acid reacts with 1 mole of acetic anhydride (Acid is catalyst of reaction).

Moles of salicylic acid are:

$5.7g\frac{1mol}{138.121g} = 0.04127 moles$

And moles of acetic anhydride are:

$9.9mL\frac{1.082g}{mL} \frac{1mol}{102.09g} = 0.105 moles$

As salicylic acid is limiting reactant, theoretical moles of acetyl salicylic acid are 0.04127mol. That means theoretical mass of acetyl salicylic acid is:

$0.04127moles\frac{180.158g}{1mol} = 7.435g$

Thus, yield of reaction is:

$\frac{5.7g}{7.435} *100=$ <em>76.7%</em>
