Which of the following is the correct formula of sulfurous acid?
The chemical formula for sulfurous acid is H2SO3.
What is chemical reaction of sulphurous acid?
Sulfuric acid reacts violently with alcohol and water to release heat. It reacts with most metals, particularly when diluted with water, to form flammable hydrogen gas, which may create an explosion hazard.
Is na2 acid or base?
NaHCO3 is a mild acid salt, H2CO3, and a solid base, NaOH. It remains undissociated because carbonic acid is a weak acid. Therefore, because of the presence of additional OH– ions formed by hydrolysis, the solution becomes basic. The chemical compound with the molecular formula Na2CO3 is sodium carbonate.
What does sulfur combine with to form sulfuric acid?
There are two industrial processes for the manufacture of sulfuric acid, both of which involve the oxidation of sulfur dioxide to sulfur trioxide and the subsequent combining of sulfur trioxide with water to form the acid. Sulfur dioxide and sulfuric acid are also serious pollutants.
What are some chemical properties of sulfuric acid?
Chemical Properties of Sulphuric Acid Sulfuric acid is a strong dibasic acid. This chemical is highly corrosive, reactive and is soluble in water. It has very low volatility. Concentrated sulfuric acid is a very strong dehydrating agent. It additionally expels water from natural mixes like starches. As it is a good oxidising agent, it can oxidise both non-metals as well as metals.
What is the equation for the reaction of sulfuric acid?
C 12 H 22 O 11 (sugar) + H 2 SO 4 (sulfuric acid) → 12 C (carbon) + 11 H 2 O (water) + mixture water and acid Although the sugar is dehydrated, the water isn’t ‘lost’ in the reaction. Some of it remains as a liquid in the acid. Since the reaction is exothermic, much of the water is boiled off as steam.
What is the pKa of HCl?
E.g., Hydrochloric acid, HCl has a pKa = -3 Acetic acid, CH3COOH has a pKa = 4.77 A strong acid is one which is largely, or completely, dissociated, and which therefore has a high Ka value (and low pKa).
