Why is NaOH unsuitable as a primary standard?

It absorbs water from the air so its weight cannot be accurately measured.

It absorbs water readily from the atmosphere, so much so that it actually forms a solution of highly concentrated NaOH, so you can never really get an accurate reading of the mass if you were to measure it.

Hope this helps!
