1. APPARATUS
1.1 Volumetric flask (500 ml capacity). : 1 No.
1.2 Measuring cylinders (100.0 ml capacity : 1 No.
1.3 Beaker (250 & 50.0 ml capacity) : One each.
1.4 Glass funnel. : 1 No.
1.5 Glass rod : 1 No.
2. REAGENTS
2.1 Nitric Acid. : LR grade
2.2 Distilled water.
3. PREPARATION
3.1 Measure 10.6 ml of Nitric Acid LR and transfer into a 50.0 ml capacity beaker.
3.2 Pour about 75.0 ml of distilled water into a 250 ml capacity beaker.
3.3 Transfer slowly, through sidewalls of the beaker, 10.6 ml of Nitric Acid LR into above said beaker, while gentle mixing, by using a glass rod.
3.4 Transfer prepared solution into a 100 ml volumetric flask by using a glass funnel.
3.5 Rinse the beakers and funnel with few ml of distilled water, and allow to add into the contents of volumetric flask.
3.6 Make up the volumetric flask to mark with distilled water, remove the funnel, keep the lid to close the volumetric flask and shake gently to mix the solution.
3.7 Transfer the prepared solution into a suitable container and label with all necessary details.
3.8 The resultant solution is having the concentration of about 10.0% w/w.
