That is solution is 1N NaOH when 40g NaOH is dissolved in 1L water.įor our purpose, weigh 20g of NaOH and dissolve it in 500ml water.ĭone. How do you prepare 0.5 N NaOH solution Molar mass of NaOH is roughly 40 gmol. Without water and the resulting ionization of NH3, anhydrous ammonia does not (can not) exhibit a pH. In pure anhydrous ammonia, by definition, there is no water, so pH measurements, which are only possible for aqueous solutions, are not possible. How do you prepare 1m ammonia solution What is the pH of anhydrous ammonia The pH of anhydrous ammonia can not be measured. How do you prepare ammonium chloride Mix ammonia with a solution of hydrochloric acid, then evaporate the solution. What amount of NaOH is required to prepare 1N NaOH solution and why only that amount is used 40 grams, this is the 1M NaOH standard laboratory solution.
An equivalent weight is equal to the molecular weight divided by the valence (replaceable H ions).
