To calculate the acid concentration of a sample of acid rain given its pH, you need to use the concept of pH and the equation relating pH to acid concentration. Here's what you can do:
1. Understand the pH scale: The pH scale measures the acidity or alkalinity of a solution. It ranges from 0 to 14, where pH 0-6.99 indicates acidity, pH 7 is neutral, and pH 7.01-14 indicates alkalinity.
2. Use the equation: The pH of a solution is defined as the negative logarithm (base 10) of the hydrogen ion concentration ([H+]) in moles per liter. The equation is: pH = -log[H+]
3. Rearrange the equation: To find the hydrogen ion concentration, rearrange the equation: [H+] = 10^(-pH)
4. Substitute the given pH value: In this case, the given pH is 4.20. Plug the value into the equation: [H+] = 10^(-4.20)
5. Use a calculator: Calculate 10 raised to the power of -4.20. The result is the hydrogen ion concentration.
After calculating the hydrogen ion concentration, you will have determined the acid concentration of the sample of acid rain.
