Specimen Question Papers and Mark Schemes
These specimen assessment materials are intended to accompany the OCR Advanced Subsidiary GCE
and Advanced GCE specifications in Chemistry (Salters) for teaching from September 2000.
Centres are permitted to copy material from this booklet for their own internal use.
The GCE awarding bodies have prepared new specifications to incorporate the range of features
required by new GCE and subject criteria. The specimen assessment material accompanying the new
specifications is provided to give centres a reasonable idea of the general shape and character of the
planned question papers in advance of the first operational examination.

Specimen Paper
Candidates answer on the question paper.
Additional materials:
Data Booklet for Chemistry (Salters)
To be brought by candidate: electronic calculator
TIME 1 hour 30 minutes
INSTRUCTIONS TO CANDIDATES
Write your name, Centre number and candidate number in the spaces at the top of this
page.
Answer all questions.
Write your answers in the spaces provided on the question paper.
There should be ample space for your answers. If you need more space for answers or
rough work you may use the blank spaces at the end of questions or any blank pages.
Rough work that is not to be marked should be crossed out.
You will be awarded marks for the quality of your written communication where an
answer requires a piece of extended writing.
INFORMATION FOR CANDIDATES
The number of marks is given in brackets [ ] at the end of each question or part question.
A copy of the Periodic Table and other tables of information are provided in a data
booklet for use with this examination; other necessary data are given as required in the
questions.
You may use an electronic calculator.

, Answer all questions.
1. Bone consists of a complex mixture of calcium salts, such as calcium carbonate, and
other material. If bone is strongly heated, the calcium salts turn into calcium oxide,
CaO. This can be separated from the other material by dissolving it in dilute
hydrochloric acid, to form calcium chloride, CaCl2 , solution.
(a) (i) Draw a flow diagram to show how calcium carbonate in bone is turned
into calcium chloride. Show the formulae of the compounds connected by
labelled arrows.
[3]
(ii) Complete and balance the chemical equation for the reaction between solid
calcium oxide and dilute hydrochloric acid, showing state symbols.
CaO + HCl →
[2]
(b) An experiment showed that 14.4 g of calcium oxide were made from a sample
of bone of mass 50.0 g. (Ar: Ca, 40; O, 16)
Calculate:
(i) the amount in moles of CaO in 14.4 g;
