The molarity of barium hydroxide solution is 0.2145 M .
What is molarity?
The proportion of solute moles to solution length is called molarity. Divide the number of moles of HCl by the volume (L) of the solution in which it was dissolved to get the molarity of the acid solution.
What is barium hydroxide ?
Ba(OH)2 is the chemical formula for barium hydroxide, often known as baryta. The powder is an odourless, transparent white colour. The nature of it is toxic. It is ionic in nature; for instance, barium hydroxide, Ba(OH)2, can produce two hydroxide ions per molecule when dissolved in water.
M1*V1 = M2*V2
a.) M1*27.6 /1000 = 0.176*20.5/1000
M1 = 0.1307
b.) M1*19/1000 = 0.154*23.9/1000
M1 = 0.1937
c.) 0.119*24.7 = 2*M2*13.7
M2 = 0.10727
a) molarity of the hydrochloric acid solution = ( volume of base * molarity of base) / ( volume of acid ) = ( 20.5 * 0.176) / (27.6) = 0.1307 M
b) molarity of the hydrochloric acid solution = ( volume of base * molarity of base) / ( volume of acid ) = ( 23.9 * 0.154 / (19) = 0.19371 M
c) molarity of barium hydroxide solution = ( volume of acid * molarity of acid) / ( volume of base ) = ( 24.7 * 0.119) / (13.7) = 0.2145 M
Therefore, molarity of barium hydroxide solution is 0.2145 M .
