The concentration of Ascorbic acid in lemons, oranges, lemon juice, orange juice and a Berocca tablet were calculated to determine the best way to receive the recommended daily intake of Ascorbic acid.
This experiment was conducted to decide the best source of Ascorbic acid for pregnant women, which is available from a supermarket. The concentrations were finalised by titrating the five substances and then calculating the concentration of Ascorbic acid. It was found that lemons had the highest concentration of Ascorbic acid, which was 0.6175mol/L. The fresh lemon was followed by the Berocca tablet, which had a concentration of 0.585mol/L, lemon juice with 0.5625mol/L, orange with 0.105mol/L, and finally orange juice, which had 0.095mol/L. While the lemon had the highest concentration, it was decided that fresh oranges were the best source of Ascorbic acid for pregnant women. These findings are significant because many pregnant women do not receive the recommended daily intake of Ascorbic acid, which has detrimental health impacts on themselves, and their child.

Zusammenfassung der Kapitel (Chapter Summaries)
Introduction: This chapter introduces the experiment's aim: to compare the ascorbic acid concentration in lemons, oranges, their juices, and Berocca tablets to determine the best source for pregnant women. It highlights the prevalence of misconceptions regarding ascorbic acid content in various products and the need for evidence-based recommendations for optimal intake during pregnancy. The chapter sets the stage for the experimental investigation that will follow.
Body: This section lays the groundwork for the experiment by covering the fundamental concepts of acids and bases, including the Arrhenius, Brønsted-Lowry theories. It explains strong and weak acids/bases, the pH scale, and the properties of acids and bases. This background knowledge is essential to understanding the titration method used to determine the ascorbic acid concentrations in the subsequent experimental chapter. The different properties of acids and bases, like their taste and reaction with litmus paper, are also discussed. This extensive background information provides a sound foundation for interpreting the experimental results.
Experiment: This chapter details the methodology employed to determine ascorbic acid concentrations. It outlines the aim, hypothesis, materials, methodology, experimental setup, and results of the experiment. The detailed description allows for the replication of the experiment and the verification of the results. The specific procedures and techniques used in the experiment are meticulously explained, providing a clear and transparent account of the scientific investigation.
Discussion: This chapter (presumably) will analyze the experimental results, interpreting the findings in the context of the theoretical background established earlier. It will likely discuss the limitations of the experiment, potential sources of error, and the implications of the results. A thorough comparison of the ascorbic acid content across different sources will be discussed and the overall significance of these findings for pregnant women's health will be highlighted.
