In HSO4- sulfur's oxidation state is +5.
By dissolving 2.0 moles of the compound in water and then, after complete dissolution, fill it up to a total volume 1.0 L with water.
Forces in chemistry are electrical forces.
This ratio is 1:2.
Sodium hydroxide is the limiting reagent.
0.5 M
Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.
From the balanced equation it can be seen that it takes 2 moles KOH to react with each 1 mole of MgCl2. So, the answer is 2.
