WebTake about 500 ml of anhydrous glacial acetic acid & about 25 ml Acetic anhydride in a cleaned and dried 1000 ml volumetric flask. Add about 8.5 ml of Perchloric acid (About 70%) with continues stirring. Cool the solution. Make up the volume 1000-ml with anhydrous glacial acid. Mix solution thoroughly. WebCorrect option is B) For acids, Normality = molarity × basicity. So, Normality = 0.3×2=0.6. ∵ Basicity of H 3PO 3 is 2 because one of the H is not replaceable in H3PO3. The H atoms which are linked to oxygen are replaceable, but H atom linked directly to central atom P is nonreplaceable. Hence, the correct option is B. chlorhexamed 0 2% alkoholfreiWebThe 'Normality' of a solution is the 'Molarity' multiplied by the number of equivalents per mole, thus for HNO3 where contain one acidic protons (H+ Ions), so 1M of HNO3 = 1N of … chlorhexamed 0 2% 300ml
