Question: The pH scale for acidity is defined by pH = - log10 [H] where [H ] is the concentration of hydrogen ions measured in moles

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 solution has a pHI of 2.05. Calculate the concentration of hydrogen ions in moles per liter (M). Write the answer in scientific notation. The concentration of hydrogen ions is moles per liter. Enter you answer to 4 significant figures (the first non-zero digit and three more for example, 0.000001234)
