Ammonium nitrate - Wikipedia

Production, reactions and crystalline phases. The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: HNO 3 + NH 3 → NH 4 NO 3. Ammonia is used in its anhydrous form (a gas) and the nitric acid is concentrated. The reaction is violent owing to its highly exothermic nature. After the solution is formed, typically at about 83% concentration, the excess water is evaporated off to leave an ammonium nitrate …

This reaction is a redox reaction (oxidation - reduction reaction). Equation of reaction of Ag and hot concentrated HNO 3. Ag + HNO 3 → AgNO 3 + NO 2 + H 2 O. In this reaction, silver is oxidized to +1 oxidation state of silver. Meanwhile nitric acid is reduced to …

How do you calculate electrochemical cell potential

Dec 22, 2013· Warning! VERY long answer! You can calculate the cell potential for an electrochemical cell from the half-reactions and the operating conditions. > The first step is to determine the cell potential at its standard state — concentrations of 1 mol/L and pressures of 1 atm at 25°C. The procedure is: Write the oxidation and reduction half-reactions for the cell.

concentration and the sulfate ion concentration would be restored to about 2.4∙10-5. This statement is the basis of Le Chatlier’s Principle. When an equilibrium position of a reaction is disturbed, a new equilibrium position will be established by shifting the reaction in a direction that alleviates the stress caused by the disturbance

Neutralization (chemistry) - Wikipedia

In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution. The pH of the neutralized solution depends on the acid strength of the reactants.

Nitric Acid (HNO3) Neutralization. pH Neutralization

Nitric Acid HNO 3: With a pKa of zero (or nearly so) HNO 3 is a very strong acid that fully disassociates at all concentrations. At higher concentrations (>5%) the outgassing of HNO 3 can be quite significant and good ventilation is required. The pH neutralization of Nitric acid is conventional and any inorganic base such as sodium hydroxide or lime can be used.

Electrochemical Reactions - Purdue University

Within each half-cell, reaction occurs on the surface of the metal electrode. At the zinc electrode, zinc atoms are oxidized to form Zn 2+ ions, which go into solution. The electrons liberated in this reaction flow through the zinc metal until they reach the wire that connects the zinc electrode to the platinum wire.

REACTION OF ACIDS WITH METALS. General word equation: metal + acid ==> a salt + hydrogen The salt, and its name, depends on the metal and acid used in the reaction and the acid is neutralised in the process.; e.g. the grey-silvery solid zinc dissolves in hydrochloric acid with effervescence to evolve hydrogen gas and leave a colourless solution of the salt zinc chloride.

Acid Rain - Department of Chemistry

Natural Acidity of Rainwater. Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H +) concentration.]The acidity of rainwater comes from the natural presence of three substances (CO 2, NO, and SO 2) found in the troposphere (the lowest layer of the atmosphere).
