Calculate the molar concentration of acetic acid (CHcCOOH) in the vineagar sample using the average volume of NaOH.
Assume that the density of vinegar is 1.00 g/mol.
Average volume of NaOH- 27.88
nicotinic acid (niacin) is a monoprotic acid with the formula HC6H4NO2. A solution that is 0.012M in the nicotinic acid has a pH of 3.30 at 25C. what is the acid-ionization constant, Ka and pKa for this acid at 25C?
To calculate the molar concentration of acetic acid in the vinegar sample, we need some additional information:
1. The balanced chemical equation for the reaction between acetic acid and sodium hydroxide is:
CH3COOH + NaOH → CH3COONa + H2O
2. The molar ratio between acetic acid and sodium hydroxide in the reaction equation is 1:1, meaning that one mole of acetic acid reacts with one mole of sodium hydroxide.
3. The concentration of the sodium hydroxide solution used is needed to perform the calculation. If you have this information, please provide it.
With these details, we can proceed with the calculation.
