NaOH is available in concentrations of up to 50%, which is the most commonly used concentration. One must be careful when using 50% NaOH because of the freezing point. NaOH at a 50% concentration will begin to freeze at temperatures below 60 0 F. This happens to be a very common problem and can render a system useless.
