What's the difference and which is better? How do you know how much to use? Is there a formula for water volume and plate area to determine the amount?

from what i read, KOH is better than NaOH.....Quote:

the concentration of KOH or NaOH solution mainly depends on the placement of ur plates...
if the spacing between each plates is very small, then u need less KOH concentration.
formula to calculate ur concentration (%w/v); dH2O = distilled water
5g KOH + 100ml (dH2O) = 5 / 100 x 100% = 5%w/v KOH solution
10g KOH + 100ml (dH2O) = 10 / 100 x 100% = 10%w/v KOH solution
