What Is 0 1 N NaOH?
What is 0 1 n naoh
Sodium hydroxide (NaOH) is an acid and base with a reputation for being quite hygroscopic. This is because it absorbs and binds water. This makes it a great candidate for being a good storage medium.
NaOH has a rounded molar mass of M(NaOH) = 40 g/mol, so it takes only 1.99 g to make a 0.1 molecular weight (MMW) solution in a one liter volume. This is a squeaky clean number and is an important unit of measure for many lab tasks, especially for titrating SO2 and other oxidants.
The best way to standardize your NaOH is by using a titration rod and measuring the resulting volume. This is not as easy as it sounds, but the results can be useful for a number of tasks, from determining pH to titrating phenols or ethyl acetate.
There are some other ways to go about titrating a naoh solution, but this is the most efficient and cost effective method. To do it the right way, fill a sterile 25 ml buret with a 0.1 N NaOH solution and record its initial volume. Then add 90 ml of deionized/distilled water to make up the volume to 100 ml.
