Would the concentration of hydroxide ion in a 0.30 m solution of potassium hydroxide (koh) be greater than, less than, or equal

patriot [66]

Potassium hydroxide KOH is a strong base which can completely ionize to form potassium and hydroxide ions.

The equation representing ionization of KOH,

$KOH(aq)-->K^{+}(aq)+OH^{-}(aq)$

The mole ratio of hydroxide to KOH from the above equation is $\frac{1molOH^{-} }{1molKOH}$

The given concentration of KOH solution=0.30M

Calculating the concentration of hydroxide ions present in 0.30M KOH solution:

$\frac{0.30mol KOH}{L} *\frac{1mol OH^{-} }{1 mol KOH} =0.30\frac{mol}{L}OH^{-}$

Therefore the concentration of hydroxide ion will be equal to 0.30 M in a 0.30 M KOH solution.

If you use one more of N2 how many moles of NH3 could be produced?

mote1985 [20]

Hey there!

2 moles will be produced.

In N₂ there are 2 nitrogen atoms. In NH₃ there is 1 nitrogen atom.

So, there will be twice as many moles produced because there will be twice as many molecules.

Hope this helps!
