Question

bobpursley · Accepted Answer

Moles of base per liter= 4/40
Molarity of base= 0.1M

Molaritybase*volumebase=MolarityAcid*volumeacid (both are monoprotic)
0.1*25cm^3=Molarityacid*24cm^3.
molarity acid=.1*25/24
massacid/liter= 40*.1*25/24=4.17 grams/dm^3

Alamin · Answer

A is a solution of trioxonitrate(v) acid, HNO3, of unknown concentration. B is standard solution of sodium hydroxide containing 4.00g per dm3 of solution. 25cm3 portions solution B required an average of 24.00cm3 of solution A for neutralization, using 2drops of methyl orange.
a: write a balanced equation for the reaction?
b:Calulate the concentration of solution B in moles per dm3 ?
c: calculate the concentration of solution A in moles per dm3
d: calculate the concentration in g/dm3 of HNO3 in solution A. (H=1, N=14, O=16, Na=23
