Ever heard of acid rain? This is rainfall with a very low pH. Write an application that will enable you to display the pH level for a swimming pool and whether an additive is needed or not. The pH is a measure of how acidic or basic the water is and is typically give on a 0-14 scale. Below 7.0 is defined as acidic, with 7 being natural. Levels much above 7 are said to be basic or alkaline. Everything that enters a pool has a pH value. To have pH in balance the water is adjusted with additions of pH increasers(bases) or pH decreasers (acids) to achieve the range of 7.2-7.8. Allow the user to input the pH level number. Display a message indicating the health(i.e., acidic, neutral, alkaline) and whether an additive is required. If an additive is required, identify the type. The water should be described as acidic, requiring bases, when the pH is lower than 7. Consider the pH as neutral for pH levels greater than 7.8 Display an appropriate message when invalid values are entered.
