What does koh do as a reagent?

What does koh do as a reagent?

1 Answer. Aqueous KOH is alkaline in nature i.e. it dissociates to produce a hydroxide ion. These hydroxide ions act as a strong nucleophile and replace the halogen atom in an alkyl halide. This results in the formation of alcohol molecules and the reaction is known as nucleophilic substitution reaction.

How is KOH concentration calculated?

a solution of koh (strong base) has a pH= 12.64 what is the concentration of koh?

  1. pOH = -log10[OH-(aq)]
  2. 1.36 = -log10[OH-(aq)]
  3. [OH-(aq)] = 0.044 mol dm-3

What happens when you add KOH to water?

Potassium metal reacts very rapidly with water to form a colourless solution of potassium hydroxide (KOH) and hydrogen gas (H2). The reaction is exothermic. Early in the reaction, the potassium metal becomes so hot that it catches fire and burns with a characteristic pale lilac colour.

How do you dissolve Koh?

Ethanol will be a suitable solvent to dissolve the KOH. Potassium hydroxide is soluble in ethanol, phenol, and glycerol; and their aq.

Does koh get rid of Mould?

I have use two products to remove mildew from my bathroom walls with great results. I did use Koh cleaning product and I added 2 drops of Clove oil. Clove oil is great for killing the mildew spores. This time I used 1 cup of vinegar, 5 drops of clove oil and a paper towel to wipe.

Does bleach kill Mould spores?

You can use bleach to remove traces of mold on tub and tile surfaces, which are hard and impermeable. However, bleach can’t kill mold on porous surfaces, such as those made of wood. That’s because mold spreads its roots deep into porous surfaces.

Why you shouldn’t use bleach on mold?

First, bleach encourages toxic mold growth on porous surfaces because it provides excess moisture. Bleach contains about 90% water. When you apply bleach to a surface, the chlorine quickly evaporates leaving behind a lot of water. So, bleach can actually make your mold problem worse.
