What is an example of a neutralization reaction?

The answer to your question is below

Explanation:

A neutralization reaction is a chemical reaction between an acid and a base, and the products will be a binary or tertiary salt and water.

Examples

a)                     HCl  +  NaOH  ⇒  NaCl  +  H₂O

b)                     H₂SO₄  + 2KOH  ⇒  K₂SO₄  +  2H₂O

c)                    2HNO₃  + Ca(OH)₂  ⇒  Ca(NO₃)₂  +  2H₂O

The molar concentration of Fe²⁺ in the original solution is 1.33 molar

Explanation:

Moles of K₂Cr₂O₇ = Molarity x Volume (lit)

                             = 0.025 x 35.5 x 10⁻³

                             = 0.0008875

Cr₂O₇²⁻ + 6 Fe²⁺ + 14 H⁺ → 2 Cr³⁺ + 6 Fe³⁺ + 7 H₂O

From equation

              1 mole K₂Cr₂O₇ used for the oxidation of 6 moles Fe²

0.0008875 mole K₂Cr₂O₇ used for the oxidation of = = 0.005325 mole of  Fe²

      Molarity =

Molar concentration of  Fe² = = 1.33 molar

So molar concentration of Fe²⁺ in the original solution = 1.33 molar
