Answer :
Molarity of the perchloric acid solution is 0.168 m
It is given that
molarity of sodium hydroxide = 0.103 m
volume of sodium hydroxide = 25.8 ml
volume of perchloric acid = 15.8 ml
molarity of perchloric acid = ?
A pH indicator plays a crucial role in monitoring a given acid-base reaction. The example of acid-base titration is expressed as:
HClO4 + NaOH -------> NaClO4 + H2O
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of a solution.
Ma x Va = Mb x Vb
Ma x 15.8 = 0.103 x 25.8
Ma = 0.168 m
Hence, molarity of the perchloric acid solution is 0.168 m
