DOES IT INFLUENCE MUCH IF SODIUM CHLORITE IS 24,5% OR 22,5%?

The effect is quite minimal and barely noticeable. Additionally, if you happen to get a drop wrong during the process, the resulting outcome does not change much either way. It is important to understand that concentration does not necessarily indicate purity in this context. Good quality sodium chlorite typically contains only 1% or less of sodium chlorate (NaClO3), which is a crucial detail to keep in mind when assessing the quality of the substance.
