The forum rules require you show some of your own work so that we may teach you

What can you say about what will happen when Potassium hydroxide (KOH) is mixed with water based on the references already provided

From the references
For KOH (caustic Potash)
Solubility in water 1210 g/L (25 °C) 1780 g/L (100 °C)

Just as a comparison

For NaCl (table salt)
Solubility in water 359 g L−1

Here is a discussion of Solubility
http://en.wikipedia.org/wiki/Solubility

From the other link provided about electrolysis what do you think will happen
Quote
Strong acids such as sulfuric acid (H2SO4), and strong bases such as potassium hydroxide (KOH), and sodium hydroxide (NaOH) are frequently used as electrolytes due to their strong conducting abilities.

Hint

Quote
Overall reaction: 2 H2O(l) → 2 H2(g) + O2(g)

Does this help
