WebSaponification value or saponification number (SV or SN) represents the number of milligrams of potassium hydroxide (KOH) or sodium hydroxide (NaOH) required to … WebSep 25, 2024 · Find the normality of 0.321 g sodium carbonate in a 250 mL solution. To solve this problem, you need to know the formula for sodium carbonate. Once you realize there are two sodium ions per carbonate ion, the problem is simple: N = 0.321 g Na 2 CO 3 x (1 mol/105.99 g) x (2 eq/1 mol) N = 0.1886 eq/0.2500 L. N = 0.0755 N. sharp pains in stomach while pregnant
