The equilibrium price before the tax is $80.
(1aii)
At the equilibrium price of $80 (where S₀ intersects D), the
quantity demanded and supplied is 60 units.
(1aiii)
The new equilibrium price is $100.
(1aiv)
At the new equilibrium price of $100, the quantity
demanded and supplied is 54 units.
(1bi)
-Price after tax = $100
-Sellers receive = $75 (where S₁ intersects the original
supply curve S₀ at the new quantity)
Tax per unit = $100 – $75 = $25
(1bii)
The amount retained per unit by the sellers after tax is the
price that sellers receive after tax. This is where the new
supply curve (S₁) intersects the original supply curve (S₀)
at the new quantity of 54 units, which is $75.
(1ci)
-Buyers pay more than the original price after tax.
-Increase in price for buyers: $100 (price after tax) – $80
(price before tax) = $20
Percentage of the tax paid by buyers per unit:
(Buyer’s portion of the tax)/(total tax) × 100
(20/25) × 100 =80%
(1cii)
-Sellers receive less than the original price after tax.
-Decrease in price for sellers: $80 (price before tax) – $75
(price after tax) = $5
Percentage of the tax paid by sellers per unit:
(Seller’s portion of the tax)/(total tax) × 100
(5/25) × 100 =20%

2024 WAEC CHEMISTRY ANSWERS
(1a)
An electrochemical cell is a device that converts chemical
energy into electrical energy or vice versa. It consists of two
half-cells, each containing a electrodes (an anode and a
cathode) immersed in an electrolyte, which facilitates the
flow of ions between the electrodes.
(1b)
(i)Spontaneity: Electrochemical cells are spontaneous,
meaning they generate electricity on their own, while
electrolytic cells require an external power source to drive
the reaction.
(ii)Direction of Electron Flow: In electrochemical cells,
electrons flow from the anode to the cathode, while in
electrolytic cells, electrons flow from the cathode to the
anode.
(iii)Purpose: Electrochemical cells are used to generate
electricity, while electrolytic cells are used to drive non-
spontaneous reactions, such as electroplating or water
splittings.
(1c)
(i)The blue color of the copper sulfate solution starts to fade
as zinc replaces the copper.
(ii)Solid copper begins to precipitate out of the solution,
forming a reddish-brown deposit at the bottom of the
beaker.
(iii)The solution might gradually become colorless if all the
copper ions are replaced.
(iv)Bubbles of hydrogen gas may be observed if the zinc is
in excess, indicating the occurrence of further reactions
involving the zinc and the sulfate or the acidic solution.
