A particular Lake contains 10^10 liter of water. Due to acidification, the pH of the Lake is 5.00. It has been decided to add enough calcium carbonate to the lake to bring the pH to 6.00.a.calculate the initial concentration (moles/L) of hydrogen, H+, ions in the lake,10^10 L, when the pH was 5.00b. What was the total number of moles of H+ ions in the lake initally?c. Calculate the final concentration (moles/L) of hydrogen, H+, ions in the lake when the pH was 6.00d. What would be the total number of moles of H+ ions in the lake after the pH was raised to 6.00?e. using the answers from b and d calculate the number of moles of hydrogen ions removed from the lake.
