Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than 7 is acidic. Materials: * pH strips
