When mixed HCl an acid and NaOH a base will react with each other. a) Write the balanced neutrali zation equation for this reaction b) What volume of 0.812 M HCl is required to titrate 1.33 g of NaOH to the endpoint?
"A student titrated a 10 mL sample of a saturated solution of borax. If the titration required 23.95 mL of 0.2556 M HCL to reach the endpoint, calculate the equilibrium molar concentration of B4O5(OH)(4 in the saturated solution"
