Write the equations for the chemical reactions of the interaction of dilute and concentrated nitric acid with potassium.

Consider the reaction of potassium with nitric acid:
1.K + HNO3 (conc.) = KNO3 + NO2 + H2O
Let’s compose electronic equations:
Oxidation K-e = K + | one;
Recovery N5 + + e = N4 + | 1
Let’s arrange the coefficients:
K + 2HNO3 (conc.) = KNO3 + NO2 + H2O
Oxygen test 6 = 6
2.K + HNO3 (p – p) = KNO3 + NH4NO3 + H2O
Let’s compose electronic equations:
Oxidation K-e = K + | 1
Recovery N5 + + 8e = N-1 | 1
Molecular Equation:
8K + 10HNO3 (P-P) = 8KNO3 + NH4NO3 + 3H2O
Oxygen test 30 = 30
