& MARK SCHEME ACTUAL EXAM
PAPER 2026 QUESTIONS WITH ANSWERS
GRADED A+
◍ What are titrations used for?.
Answer: Titrations are used to find the exact volumes of acid and alkali that
react with each other
◍ OILRIG.
Answer: Oxidation Is Loss of electronsReduction Is Gain of elections
◍ pH scale.
Answer: A measure of acidity or alkalinity of water soluble substances
◍ What is a mixture?.
Answer: A mixture is a substance with different elements or compounds not
chemically combined
◍ How do you make copper salt?.
Answer: Add copper oxide to sulphuric acid and stir, warm gently. The
solution turns blue showing that copper sulphate is being formed, excess
black copper oxide can be seen. Filter the solution to remove excess copper
oxide and evaporate the water so that crystals of copper sulphate start to
form. Stop heating when you see the first crystals appear at the edge of the
solution , leave the rest of the water to evaporate, this gives you large
crystals. Any small excess of solution on the crystals can be removed by
dabbing between filter papers, then leaving to dry
,◍ What type of ions do salts contain?.
Answer: Salts contain a positive ion which comes from the base or alkali
and a negative ion which comes from the acid
◍ Describe the reaction of a group 1 metal and chlorine in terms of electrons.
Answer: In the reaction a group 1 metal transfers its outer electron to the
chlorine, now both atoms have a full outer energy level. The metals have a
1+ charge and the chlorine has a 1- charge
◍ How many bonds does Carbon form?.
Answer: Carbon forms 4 bonds
◍ anion.
Answer: negatively charged ion
◍ Do giant covalent molecules have high or low melting and boiling points?.
Answer: Giant covalent molecules have high melting and boiling points
because they have millions of strong covalent bonds
◍ balanced equation.
Answer: A balanced chemical equation occurs when the number of the
different atoms of elements on the reactants side is equal to that of the
products side.
◍ Copper, silver, gold.
Answer: Unreactive metals which do not react with water at all
◍ vaporization.
Answer: The process by which a liquid changes into a gas/vapor as a result
of energy being absorbed.
◍ Why do ionic compounds have high melting and boiling points?.
Answer: Tonic compounds have high melting and boiling points because the
strong electrostatic forces require a lot of heat energy to break
◍ neutralisation.
Answer: The reaction between an acid and a base. Typically produces a salt
and water.
, ◍ Why can't ionic compounds conduct electricity when they are solids?.
Answer: Ionic compounds can't conduct electricity when they are solids
because the ions cannot move, they are locked in place by strong
electrostatic forces
◍ reactivity series.
Answer: a calculated progression of a series of metals, arranged by their
"reactivity" from highest to lowest.
◍ 2,8,8.
Answer: max number of electrons in first three energy levels
◍ Endothermic.
Answer: Shown by a fall in temperature, a reaction which takes in energy
the surroundings.
◍ Mark Scheme.
Answer: Guidelines for grading exam responses.
◍ ore.
Answer: A native mineral from which a metal or metals can be extracted.
◍ anode.
Answer: The electrode at which oxidation occurs. The positive electrode.
◍ What is the plum pudding model?.
Answer: The plum pudding model is what scientists suggested is the
structure of atoms is after the discovery of the electron
◍ How do you calculate the Mr?.
Answer: Calculate the Ar of each element and then add them all up
◍ trend.
Answer: the overall direction taken by a data path
◍ percentage yield.
Answer: (actual yield/theoretical yield) x 100
◍ electrochemical cell.
