Find the percentage of ionized substituted benzoic acid (substituted benzoate) which will be in the buffered aqueous solution with pH=5.8 if the pKa of the substituted benzoic acid is 4.7. Round your answer to the nearest integer, e.g. 1 %
Benzoic acid is a weak acid that has antimicrobial properties. Its sodium salt, sodium benzoate, is a preservative found in foods, medications, and personal hygiene products. Benzoic acid ionizes in water: C6H5COOH⇌C6H5COO−+H+ The pKa of this reaction is 4.2. In a 0.62 M solution of benzoic acid, what percentage of the molecules are ionized? Express your answer to two significant figures and include the appropriate units.
Assuming that an acid (AH) which has pKa=5.7 is added to the buffered solution with pH=6.8. Calculate percentage of non-ionized acid (AH) that will appear in the solution once the equilibrium is reached. Answer is numerical. Round the answer to the nearest whole number. Don't write % simbol in the answer.
Benzoic acid is a weak acid that has antimicrobial properties. Its sodium salt, sodium benzoate, is a preservative found in foods, medications, and personal hygiene products. Benzoic acid dissociates in water: C6H5COOH⇌C6H5COO−+H+ The pKa of this reaction is 4.2. In a 0.76 M solution of benzoic acid, what percentage of the molecules are ionized? Express the percentage numerically using two significant figures.
