When 22.63 mL of aqueous NaOH was added to 1.214 g of CHES (pKa =9.39; and MM = 207.29 g/mol) dissolved in 41.37 mL of water, the pH was 9.24. Calculate the molarity of NaOH.
Liquids "flow" quickly as measured by the speed at which a small amount of liquid will spread itself out to form a puddle. What does this behavior imply about the speeds at which the individual liquid particles are moving relative to each other?
A pH of 3.74 is reached when 18.50 mL of sodium hydroxide has been added to the acid solution. What is the molar mass of formic acid given this data?
