All of you are probably familiar with the basics of a scientific experiment. Perhaps you've helped your child out with a science fair project,
Adding more pH values (2.5 and 3.5) increased the number of data points, allowing a more detailed and continuous trend to be observed between pH and mass loss.
After the preliminary tests, improvements were made to increase reliability and validity. Teeth were dried multiple times and the lowest mass was recorded
This experiment had several strengths which improved the quality of the results. A wide range of pH values was used,
Problem: The aim of this investigation was to determine the effect of pH of phosphoric acid on tooth decay by measuring mass loss.
