Is H2Cr2O2 an acid, base, or neutral? please justify your answer with an equation showing its dissociation.
The pHpH scale for acidity is defined by pH=−log[H+]pH=-log[H+] where [H+][H+] is the concentration of hydrogen ions measured in moles per liter (mol/L).
(A) If there are 0.0079432823472428 mol/L of hydrogen ions in a certain substance, what is the pH of this substance?pH=pH= Round your answer to at least two decimal places.
(B) If there are 0.003019951720402 mol/L of hydrogen ions in a different substance, what is the pH of this substance?pH=pH= Round your answer to at least two decimal places.
The pH scale was designed to make it convenient to express hydrogen ion concentrations that are small in aqueous solutions. The definiton of pH is in
terms of base 10 logarithms.
pH = - log [H*]
where [H"] is the hydrogen ion concentration.
a If the hydrogen ion concentration in a solution is 1.97 x 10 molL, the pH is
b. If the pH of a solution is 3.146, the hydrogen ion concentration is
mol/L.
