Fill in the fractions required to determine the concentration of HCI. ( A ) L NaOH × ( B ) ( C 1 L NaOH (D 1 E) L HCI

The pH scale for acidity is defined by pH – log10 H*| where |H*| is the concentration of hydrogen ions measured in moles per liter (M). (A) The pH of Drano is 13.3. Calculate the concentration of hydrogen ions in moles per liter (M). [H*] = M (B) The pH of rain water is 5.5. Calculate the concentration of hydrogen ions in moles per liter (M). [H*] = M
