Sodium hydroxide is a strong base with the chemical formula NaOH. Ammonia water is usually a solution of NH3 and H2O mixed together to form NH4OH,. This is usually the stuff people clean with and is also a strong base. Ammonia (the gas) is just NH3.
Weigh 20g. sodium hydroxide pillets pour it into a clean and dry 1L measuring flask. Dilute it with 200 mL of distilled water vith vigourous shaking, then dilute with distilled water up to the mark of 1000mL. Stand it for few hours. Check, it should be clear solution and then standardise it with potassium hydrogen phthallate OR oxalic acid.
