vertical integration. Merger of companies at different stages of production and/or distribution in the same industry. When a company acquires its input supplier it is called backward integration. When it acquires companies in its distribution chain it is called forward integration.
What is Nitrite. Nitrites is also a polyatomic ion containing N and O atoms, where Nitrogen has an oxidation number of +3. The Nitrite group contains one Nitrogen atom and two Oxygen atoms and is represented by the molecular formula, NO2-. The O-N-O bond angle is roughly around 120Â°.
To balance the charges, we require two nitrate ions per lead (II) ion, and so lead (II) nitrate is #Pb(NO_3)_2#. The potassium ion is #K^+# and the iodide ion is #I^-#. The two charges balance in a #1 : 1# ratio, so potassium iodide is simply #KI#. In lead (II) iodide, the charges balance in a #1 : 2# ratio, so the formula is #PbI_2#. Finally, in potassium nitrate, the charges balance in another #1 : 1# ratio, giving a formula of #KNO_3#. The symbol equation is as follows:
