It is interesting to mention, that phosphoric acid can be titrated as triprotic - if PO 43- anion is precipitated first using metal ions (for example Ca 2+ or Ag + ): After

Balancing redox equations (article) | Khan Academy

To balance a redox equation using the half-reaction method, the equation is first divided into two half-reactions, one representing oxidation and one representing reduction. The equations for the half-reactions are then balanced for mass and charge and, if necessary, adjusted so that the nuer of electrons transferred in each equation is the

Displacement Reaction Definition and Examples

9/9/2019· Single displacement reactions are reactions where one reactant replaces part of the other: AB + C → AC + B. An example is the reaction between iron and copper sulfate to produce iron sulfate and copper: Fe + CuSO 4 → FeSO 4 + Cu. Here, both iron and copper have the same valence. One metal ion takes the place of the other, bonding to the

What Are the Chemical Reaction Equations for Acid Rain?

27/3/2020· The chemical reaction equation for the production of acid rain resulting from sulfur oxides is: SO 2 + HOH -> H 2 SO 3. The reaction equation for acid rain produced from nitrogen oxides is: 2NO 2 + HOH -> HNO 2 + HNO 3. Acid rain refers to any kind of precipitation that transports nitrogen and sulfur compounds to the Earth''s surface.
