Sulfuric acid is formed as a result and the resulting acid rain can damage the environment. The acidity of rain and lakes is measured using pH = − log10 (C ) where C is the concentration of hydronium ions in the water. A pH value of 7 indicates a neutral value, while levels below 7 indicate an acid and above 7 an alkaline or base. Math Function Example Algorithm: • input hydronium ion concentration • calculate pH • display results Hand calculation…consider input C = .0001 (mol/litre) pH = − log10 (.0001) = 4 Example Program: Compound Interest An investor plans to invest an amount of money p in an account with interest r (compounded...
