Resource summary

Question 1

Question
In a mixture of ions it is the ion which is [blank_start]lower[blank_end] in the reactivity series that will be discharged and gain electrons (i.e. is [blank_start]reduced[blank_end])
Answer
  • lower
  • higher
  • reduced
  • oxidised
  • thrown out of the window

Question 2

Question
So as [blank_start]hydrogen[blank_end] is lower than [blank_start]sodium[blank_end] in the reactivity series it is the [blank_start]H+[blank_end] ion which is discharged and so the element [blank_start]H2[blank_end] will be formed.
Answer
  • hydrogen
  • sodium
  • sodium
  • hydrogen
  • H+
  • Na +
  • H2
  • Na

Question 3

Question
The half equation for this is: [blank_start]2H+[blank_end] + [blank_start]2e-[blank_end] = [blank_start]H2[blank_end]
Answer
  • 2H+
  • 2e-
  • H2

Question 4

Question
At the anode [blank_start]oxygen[blank_end] is made unless a [blank_start]halide[blank_end] ion is present, in which case the [blank_start]halogen[blank_end] is made.
Answer
  • oxygen
  • halide
  • halogen

Question 5

Question
Write the half equation for the formation of oxygen (from hydroxide ions) at the anode: [blank_start]4OH-[blank_end] = [blank_start]O[blank_end]2 + 2[blank_start]H2O[blank_end] + [blank_start]4e[blank_end]-
Answer
  • 4OH-
  • O
  • H2O
  • 4e

Answer
  • Hydrogen
  • Potassium
  • Sulphur
  • Oxygen

Question 7

Question
What will be produced at the anode in the electrolysis of a potassium sulphate solution?
