On the units of alkalinity for soda ash solution
Thread Content
Today, I came across a foreign-language article in which the alkalinity of the alkali solution was given as 89 ml of N/20. My knowledge is rather limited; thus, I hope that someone more knowledgeable can enlighten me. What unit is this, and how do I convert it to mol/L? l
N should mean equivalent concentration. 1 mole of sodium hydroxide dissociates to produce 1 mole of hydroxide ions. Therefore, N/20 corresponds to a normality of 0.05 equivalents per liter. Dividing this value by 0.089 L gives the concentration in moles per liter
