The concepts of chemical reactions and stoichiometry can be applied in real-life scenarios, such as determining the amount of baking soda needed to neutralize the acidity in a swimming pool, by following these steps:1. Identify the chemical reaction: In this case, the reaction is between baking soda sodium bicarbonate, NaHCO3 and the acidic substance in the pool, which is typically hydrochloric acid HCl . The balanced chemical equation for this reaction is: NaHCO3 + HCl NaCl + H2O + CO22. Determine the concentration of acid: The pH level of the pool indicates the acidity or alkalinity of the water. A pH of 7 is neutral, while a pH below 7 is acidic, and a pH above 7 is alkaline. To determine the concentration of HCl in the pool, you can use the formula: [H+] = 10^-pH where [H+] is the concentration of hydrogen ions H+ in moles per liter M , and pH is the given pH level of the pool.3. Calculate the moles of acid: Once you have the concentration of HCl, you can calculate the moles of acid in the pool using the pool's volume: moles of HCl = [HCl] pool volume in liters 4. Use stoichiometry to determine the moles of baking soda needed: From the balanced chemical equation, we can see that one mole of NaHCO3 reacts with one mole of HCl. Therefore, the moles of baking soda needed to neutralize the acid in the pool will be equal to the moles of HCl: moles of NaHCO3 = moles of HCl5. Calculate the mass of baking soda needed: To find the mass of baking soda needed, you can use the molar mass of NaHCO3, which is approximately 84 g/mol: mass of NaHCO3 in grams = moles of NaHCO3 molar mass of NaHCO3By following these steps, you can apply the concepts of chemical reactions and stoichiometry to determine the amount of baking soda needed to neutralize the acidity in a swimming pool, given the pool's volume, pH level, and concentration of acid.
