Introduction

The ability to understand and communicate science is an integral part of your chemistry course. In your scientific literacy in chemistry exam paper, you will be given a scientific passage. You will then be asked questions which test your comprehension of the scientific passage, as well as your knowledge and understanding of the chemistry concepts you have studied throughout your A level qualification.
Throughout the course you will have extracts and manipulates data, interpreted and used information, and written logical accounts using appropriate technical terms. These are all examples of scientific literacy.
In all of your A level written assessments, you will demonstrate these skills. This may be via questions in unfamiliar contexts and might involve extended response answers.
In addition, you will be given a piece of scientific literacy in advance of the scientific literacy in chemistry exam paper. The examination will have associated questions with a particular emphasis on scientific literacy. There will also be questions assessing comprehension of and use of data from the practical insert of the Practical Skills in chemistry exam paper.

Analysing and answering chemical literacy questions

For your Scientific literacy in chemistry exam, you will be provided with a pre-release Advance notice article, which you should read carefully before the examination date. In the Scientific literacy in chemistry exam, there will be at least one question relating to the pre-release article.
To help you practice extracting information from a specific passage, such as the pre-release advances notice article, an example article is provided below, based on the Storylines content of chapter 8; Oceans. The Scientific literacy in chemistry exam paper could ask questions on ANY of the content you have studied in your course.
This activity will enable you:
- Extract and manipulate data
- Interpret and use information
- Show comprehension by written communication with regard to logical presentation and the correct use of appropriate technical terms
- Check your understanding of entropy, pH, solubility product, and equilibria.

Dissolving Seashells (Introduction)

Seashells are involved in the reactions that influence the solubility of carbon dioxide in the oceans and in this section, you are going to look at the role that they play. The three reactions below summarise what happened:
REACTION 1: CO2(g) = CO2(aq)
REACTION 2: CO2(aq) + H2O(l) = H+(aq) +HCO3-(aq) {pKa= 6.34}
REACTION 3 HCO3-(aq) = H+(aq) +CO3(2)-(aq)

Ion | Concentration/ moldm-3
Cl- | 5.46 * 10^-1
Na+ | 4.68 * 10^-1
SO4^2- | 2.81 * 10^-2
