You could replace H X 2 S O X 4 with H C l and get the same reaction. In the second equation, the same oxidation of F e to F e X 2 + by H X + also occurs. WebIn this type of reaction a salt is formed from an acid and an alkali. The reactants include elements which must also be present in the products. As the reacting alkali is potassium hydroxide, then the product will be a potassium salt. As the reacting acid is nitric acid, then the salt produced will be a nitrate. sich etwas wagen synonym

Word equations - RSC Education

Nitric acid is normally considered to be a strong acid at ambient temperatures. There is some disagreement over the value of the acid dissociation constant, though the pKa value is usually reported as less than −1. This means that the nitric acid in diluted solution is fully dissociated except in extremely acidic solutions. The pKa value rises to 1 at a temperature of 250 °C. Nitric acid can act as a base with respect to an acid such as sulfuric acid: WebFor a mixture of 100 ml of concentrated nitric acid, we added 30 ml of water, 50 g of iron filings or fine turnings in small portions. we can regulate the rate of the reaction by the rate of addition of iron and gently heating the mixture not crossing above 70-degree C. 4 Fe + 10 HNO3 → 4 Fe (NO3)3+ NH4NO3+ 3 H2O
