Calculate the molar concentration of the acid if 125 mL of hydrochloric acid was required to neutralize 45.0 mL of 0.345 M lithium hydroxide. Be sure to use a balanced equation.

Expert Solution

Balanced equation:

LiOH(aq) + HCl(aq) ---> LiCl(aq) + H2O(l)

1 mol LiOH = 1 mol HCl

No of mol of LiOH = M*V

= 45*0.345

= 15.5 mmol

No of mol of HCl required = 15.5 mmol

volume of HCl required = 125 ml

concentration of HCl = n/v

= 15.5/125

= 0.124 M

A [a]ml aliquot of a nitric acid of unknown concentration is pipetted into 125-ml Erlenmeyer flask and 2 drops of phenolphthalein are added. The [b] ml of sodium hydroxide with concentration [c]mol/l is used to titrate the nitric acid solution. What is the molar concentration (mol/l) of the nitric acid solution? For [a], [b], and [c] each student would have a different set of data. Practice how to solve this problem if [a] =20.00ml of nitric acid, [b] =17.60ml of...

Calculate the molarity of a solution made by adding 25.4 mL of concentrated hydrochloric acid (37.3 % by mass, density 1.19 g/mL) to some water in a volumetric flask, then adding water to the mark to make exactly 500 mL of solution. (It is important to add concentrated acid or base to water, rather than the other way, to minimize splashing and maximize safety.)
