## HNO3 + Ba(OH)2 titration

• HNO3 + Ba(OH)2 undergo acid base titration. Strong acid HNO3 combines with strong base Ba(OH)2 to lớn give neutralization reaction by undergoing titration of standard solution to lớn give equivalence point.
• Titration will take place as

#### Chemicals

Unknown concentration of HNO3, known concentration of Ba(OH)2.

#### Indicators

Phenolphthalein indicator is commonly used indicators for such titration.

#### Procedure

• In the first place, fill the burette all the way to lớn the tip before rinsing it with a known barium hydroxide solution.
• In this titration nitric acid is analyte and titrant are barium hydroxide, because nitric acid is in unknown amount, whose concentration we need to lớn find by the help of barium hydroxide.
• Then suck precise amount of nitric acid solution in conical flask.
• Add 2-3 drops of phenolphthalein indicator in conical flask containing unknown concentration of nitric acid.
• Then add drop by drop of known concentration of barium hydroxide solution into conical flak by means of burette, till its color changes from colorless to lớn pink.
• Note the reading n repeat it for 3 times.
• For finding normality of analyte, the formulae are given as:
• N1V1 = N2V2
• From normality value, we can find mass of nitric acid.
• Mass = Eq. Wt. × normality × volume / 1000

• Every compound’s phase should be taken into tài khoản while balancing a molecular equation.
• 2 HNO3 (Aq) + Ba(OH)2 (Aq) → Ba(NO3)2 (Aq) + 2H2O (l)
• The aqueous salts or chemicals in the equation need to lớn be made into ions. Only the strong electrolytes should be broken down since they completely dissociate.
• Here, HNO3 is strong acid, Ba(OH)2 is strong base, and Ba(NO3)2 is strong salt. So, they undergo dissociation.
• 2 H+ + 2 NO3 + Ba+2 + 2 OH → Ba+2 + 2NO3+ 2 H2O
• The spectator ions must be cancelled out in order to lớn show species, actually involved in reaction.
• The remaining substance is net ionic equation.
• OH (Aq) + H+(Aq) → H2O (l)
