What does nitric acid react with?
Carbon (C) and hot concentrated nitric acid react to give carbon dioxide (CO2), nitrogen dioxide (NO2) and water.
What happens when carbon reacts with metal?
Metal oxides are converted to usable metals when they react with carbon. The extraction of metals in a blast furnace with coke (carbon from heated charcoal) is called smelting. When electricity is used to recover a metal from a metal oxide it is called electrolysis.
Does sodium nitrate react with sulfuric acid?
Sodium nitrate reacts with sulfuric acid by the following equation during synthesis of GO: 2 NaNO3 + H2SO4 = 2 HNO3 + Na2SO4. This agent is nitric acid that produced by the above-listed rection.
What happens when Sulphur reacts with nitric acid?
When concentrated sulphuric acid is reacted with sulphur it results in the formation of sulphuric acid water and nitrogen dioxide. Here, nitric acid acts as an oxidising agent for sulphur where sulphur is oxidised into sulphur dioxide into the sulphur trioxide and eventually to sulphur acid.
What happens when carbon is boiled with conc HNO3?
Carbon react with nitric acid to produce carbon dioxide, nitrogen dioxide and water. Nitric acid – concentrated heated solution.
What are the negative effects of nitric acid?
Exposure to nitric acid can cause irritation to the eyes, skin, and mucous membrane; it can also cause delayed pulmonary edema, pneumonitis, bronchitis, and dental erosion. Nitric acid is highly corrosive. Workers may be harmed from exposure to nitric acid.
Which metal oxides Cannot be reduced by carbon?
Which oxides can be reduced by carbon?
carbon monoxide …also useful as a metallurgical reducing agent, because at high temperatures it reduces many metal oxides to the elemental metal. For example, copper(II) oxide, CuO, and iron(III) oxide, Fe2O3, are both reduced to the metal by carbon monoxide.
What type of reaction is sodium nitrate?
Sodium nitrate belongs to the family of compounds called salts, which are formed by uniting an acid (nitric in this instance) with a base (in this case sodium hydroxide). When sodium nitrate is combined with hydrochloric acid, an exchange reaction occurs, producing sodium chloride and nitric acid.
What happens when carbon and nitrogen react with nitric acid?
Carbon (C) and hot concentrated nitric acid react to give carbon dioxide (CO 2 ), nitrogen dioxide (NO 2 ) and water. Here, carbon is oxidized to its +4 oxidation state and nitrogen’s oxidation state is changed from +5 to +4. Phosphorus reacts with nitric acid to give phosphoric acid (H 3 PO 4 ), NO 2 and H 2 O. This is a redox reaction.
What is the equation for nitric acid and potassium carbonate?
Nitric acid is HNO3. Potassium carbonate is K2CO3. Nitric acid is an acid and potassium carbonate is a base, so this is an acid/base chemical reaction. The unbalanced chemical reaction is shown below. Now we must balance the elements on each side of the equation.
What happens when lead nitrate is mixed with nitric acid?
Here lead is oxidized to its +2 oxidation state. Lead nitrate is soluble in water. Carbon (C) and hot concentrated nitric acid react to give carbon dioxide (CO 2 ), nitrogen dioxide (NO 2 ) and water. Here, carbon is oxidized to its +4 oxidation state and nitrogen’s oxidation state is changed from +5 to +4.
How does nitric acid oxidation affect carbon fiber?
Nitric acid oxidations at 115°C have been shown to introduce significant surface acidity to carbon fibers [15-25].
