Take 1 litre of distilled water in a 2-lit glass beaker. Weigh out 32.0-32.5gms. Add potassium Permanganate (KMnO4 ) in a watch glass to the distilled water in the beaker. Heat the beaker on a hot plate and gently boil its conten…
Prepare a 0.1 N and a Potassium Hydrogen Phthalate Solution Materials Potassium Hydrogen Phthalate (KHP) (standard) Phenolphthalein (or another indicator) Distilled water Analytical balance Volumetric flask Burette Erlenmeyer f…
Apart from the mechanical properties of materials stated so far, another important property is corrosion resistance. All metals are thermodynamically unstable and tend to react with their environment to produce compounds such as …
This will give you a standard 0.1 N oxalic acid solution , where 1 N solution contains 1 equivalent weight of solute per litre of solution. Since the equivalent weight of oxalic acid dihydrate is 63.03 g/mol, the amount you weigh…
In chemistry, pH is a very important factor. It shows the hydrogen potential in a solution. This scale, from 0 to 14, helps measure how acidic or basic something is. It's used in water treatment, soil analysis, and more. It h…
Rapidly weigh about 10 gm of sodium hydroxide in a small beaker and dissolve it in 50 ml of distilled water. Pour the content of the beaker into a 250-ml volumetric flask and make up the volume to the mark with distilled water. T…
