Lab 4 Acids, Bases and pH A natural. pH indicator such as red cabbage is added to an aqueous clear solution with a pH value of 5. When the natural pH indicator is added, the observed color and pH value will go toward the left of neutral or toward the right of neutral on the pH scale below? Left of neutral Right of neutral

Lab 3 Properties of Water Surface tension helps some insects “skate” across the surface of the water.

Lab 4 Acids, Bases and pH A chemist measures the pH of a solution to be pH of 2.0 and compares it to the pH of black coffee at a pH of 5.0. How many times more acidic is the solution compared to the black coffee?  Show your calculation for credit. Not exponents.
