What happens if you mix sulfuric acid and nitric acid?
Nitric acid, acetone and sulfuric acid: Acetone is oxidized violently by mixed nitric-sulfuric acids, and if the mixture is confined in a narrow-mouthed vessel, it may be ejected or explode. Bretherick, L. Handbook of Reactive Chemical Hazards.
Why is H2SO4 used to prepare HNO3?
Concentrated sulphuric acid has a high boiling point (356°C). So, it is considered to be non-volatile. Hence, it is used for preparing volatile acids like Hydrochloric acid and Nitric acids from their salts by double decomposition.
Why can you not substitute h2so4 for HNO3?
Sulfuric acid cannot be substituted for nitric acid because aqua regia requires a strong oxidant, and sulfuric acid is not one; but sodium nitrate can often be used as a substitute for nitric acid.
What happens when you mix nitric acid and methanol?
Mixtures of methanol with up to 5\% nitric acid are safe to use and store in small quantities. Mixtures of methanol with more than 5\% nitric acid are subject to violent decomposition if heated. Mixtures of 33\% nitric acid in methanol have decomposed suddenly and violently. Never add nitric acid to isopropyl alcohol.
Why is concentrated h2so4 used instead of concentrated HNO3?
Hi. The sulphuric acid is used in the preparation of hydrogen chloride {HCl} and nitric acid {HNO3} because it is a non-volatile{ it has a high boiling point} and HCl and HNO3 are volatile acids.
Why is h2so4 preferred over acids?
Answer:Sulphuric acid is used. This acid is preferred to other acids because of its dehydrating properties.
What happens when you mix alcohol and nitric acid?
The alcohol can be methanol, ethanol or methylated spirits. Mixtures of ethanol and nitric acid are potentially explosive. A solution of ethanol and nitric acid will become explosive if the concentration of nitric acid reaches over 10\% (by weight). Solutions above 5\% should not be stored in closed containers.
Is hno3 an explosive?
Being a powerful oxidizing agent, nitric acid reacts violently with many non-metallic compounds, and the reactions may be explosive.
What happens when carbon is heated with concentrated h2 S o4?
Sulfuric acid interacts with carbon to generate carbon dioxide and sulphur dioxide gas, as well as water. A concentrated, heated solution of sulfuric acid should be used. Colorless carbon dioxide gas is produced when carbon is oxidised.
Why does sulfuric acid cause charring?
Sulphuric acid is strong dehydrating agent which means that it can abstract water from the substances with which it reacts. So when sulphuric acid is added to carbohydrates and sugar, it removes hydrogen and oxygen from them. And just leaving behind carbon which looks like burnt sugar that is brown in colour.
Is HNO3 a strong or weak acid?
HNO3 (nitric acid) is a strong acid. This is because it dissociates completely in water. The molecule is made up of a hydrogen atom, a nitrogen atom and three oxygen atoms. In the chemical reaction that formed the nitric acid molecules, the electron from the hydrogen atom is shared by the nitrogen-oxygen atom combination.
Is HNO3 a weak acid?
HNO3 is not a weak acid. It is in fact the strongest oxidising acid because it oxidises the hydrogen gas produced on reaction with metals higher than hydrogen in the E.C.S. to water vapor.
Why is H2SO4 stronger than H3PO4?
HCl is a stronger acid than H2S because Cl is more electronegative than S. H2AsO4- is a stronger acid than HAsO42- because it has more acidic H atoms. H3AsO4 is a stronger acid than H3PO4 because As is larger than P. HBrO3 is a stronger acid than HBrO2 because it has more oxygens surrounding the central Br atom.
What is the reaction of MG with HNO3?
Mg + HNO3 = Mg (NO3)2 + N2O + H2O | Chemical reaction and equation Magnesium react with nitric acid 4Mg + 10HNO 3 → 4Mg (NO 3) 2 + N 2 O + 5H 2 O [ Check the balance ]
