You have two solutions, A and B. The pH of solution A is 6 and pH of solution B is 8. Which solution has more hydrogen ion concentration? Which of this is acidic and which one is basic?
When pH value is less than 7 it indicates an acidic solution, while greater than 7 it indicates a basic solution. Therefore, the solution A with pH = 6 is acidic and has more hydrogen ion concentration than the solution B of pH=8 which is basic.
You are given kerosene, turpentine and water. In which of these does the light travel fastest? Use the information given in Table 10.3.
