Chemists use equivalent units, or equivalents, to express the reactive capacity of a chemical species, such as electrons or ions like H+. The equivalent defines how many electrons or ions may be transferred in a chemical reaction. For example, in the aci
To determine the equivalent weight of NaOH, first it needs to be determined what type of substance it is. NaOH is a base; therefore, the n number of equivalents is the absolute value of the number of hydroxide ions. In this case, there is 1 hydroxide ion that dissociates in water. ...
If you see "normal" as "expected," even in the chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality ...
