WebSolid NaOH absorbs so much moisture from the air that a measured compound sample is never 100% NaOH. On the other hand, the acid salt potassium hydrogen phthalate, KHC8H4O4, can be measured out in precise mass amounts. It reacts with NaOH in a simple 1:1 stoichiometric ratio, thus making it an ideal substance to standardize a NaOH solution. WebExamples: Calculate the percent mass of a solution of 5 g NaOH in 95 g of H2O. % mass = 5 g NaOH / (5g + 95g) solution x 100% % mass = 5 g NaOH/ 100 g solution x 100%% mass = 0.05 x 100%% mass = 5% NaOH Calculate the percent volume of a solution of 25 ml ofFeSO4in 175 ml of H2O. college grants for breast cancer survivors

WebApr 5, 2012 · Hi I am new here, my Q is as per your explanations in the earlier post, to make a 50% concentration of NaOH solution, i should add 500gm of pellets and 500 ml of water. Is this correct. I also need to know , if i heat this liquid to (1) 100 deg C or (2) 160 deg C what will happen. ... E.g 160 gram of sodium hydroxide and 840 gram of distilled ...
