Why sulphuric acid is called as King of chemicals?

Sulphuric acid is called "king of acids" because of its direct and indirect applications in the manufacture of many chemicals including fertilizers. Sulphuric acid is used to clean up rust from steel rolls and soap. It also dissolves its compounds. Thus, it is ideal to call sulphuric acid as king of chemicals.

Does sulfuric acid lower pH?

The cheapest way to lower the soil pH is to add elemental sulfur to the soil. Soil bacteria change the sulfur to sulfuric acid, lowering the soil pH. If the soil pH is greater than 5.5, apply elemental sulfur (S) to decrease the soil pH to 4.5 (see Table 1). Is sulfuric acid toxic? Sulfuric acid is a highly corrosive chemical that is potentially explosive in concentrated form. It can cause severe skin burns, can irritate the nose and throat and cause difficulties breathing if inhaled, can burn the eyes and possibly cause blindness, and can burn holes in the stomach if swallowed.

Then, does sulfuric acid expand when frozen?

And post graduation diploma in analytical chemistry! Yes it does. The melting point of sulphuric acid is 10? so it freezes below 10?. And its boiling point is 337? so it boils and vaporises too. And another question, does sulfuric acid weaken over time? Sulfuric acid, H2SO4, is hygroscopic. It will absorb moisture from the air. So if a container of H2SO4 is left open, it will become more diluted over time.

Subsequently, does sulfuric acid lose its potency over time?

Indefinite IF there is nothing for the sulfuric acid to react with - no impurities, nothing to react with in the container material, no contact with the atmosphere. Sulfuric acid is very stable - no internal reactions when there are no impurities. Accordingly, what will sulfuric acid eat through? Reactivity. Sulfuric acid is very reactive and dissolves most metals, it is a concentrated acid that oxidizes, dehydrates, or sulfonates most organic compounds, often causes charring. Sulfuric acid reacts violently with alcohol and water to release heat.
