titration of 17.85 ml of nitric acid solution require 16ml of 0.16 M KOH solution. what is the polarity of the acid?
HNO3(aq) + KOH (aq)--------------------> KNO3(aq) + H2O(l)
1 mole 1 mole
HNO3 KOH
M1 = M2 = 0.16M
V1 = 17.85ml V2 = 16ml
n1 = 1 n2 = 1
M1V1/n1 = M2V2/n2
M1 = M2V2n1/V1n2
= 0.16*16*1/17.85*1
= 0.1434M
molarity of HNO3 = 0.1434M >>>>answer
