Why can concentrated H2SO4 and HNO3 not be used for laboratory preparation of H2S?
They can. Either one of these acids will produce Hydrogen Sulfide when reacted with a metal sulfide. The reaction is extremely vigorous and even violently so. It is thus best they are used dilute for safety. Also, these acids are oxidizing and H2S is reducing so it is not an efficient process. HCl or acetic acid etc are far better to use.
What else can I help you with?
How do you valance s plus hno3 equals so2 plus no2 plus h2o?
10S + 40 HNO3 → 10 H2SO4 + 40 NO2 + H2OS + 6HNO3 → H2SO4 + 6NO2 + 2H2OS + 4HNO3 -→ SO2 + 4NO2 + 2H2O
Chemical formula for acid rain?
It is actually a mixture of very dilute H2SO4 and HNO3
Is rain and acid a rock chemical?
An acid rain contain acids as HNO3, H2SO4, HCl.
What are the names of all acids?
petil gas and liquid to all those who didn't know and who are dumb
What are some examples of acids and their chemical formulas?
A couple of definitions of acids:1. a substance which forms H+ ions in solution2. a proton donor some chemical formulas for acids- H2SO4 sulfuric acid- HCl hydrochloric acid- HNO3 nitric acidSee the Related Questions to the left for more information and other examples.
How can you differentiate between H2SO4 and HNO3?
by adding AgNO3, ppt. is formed in h2so4 not hno3.
What happens when phenol reacts with concentrated HNO3 plus H2SO4?
When phenol reacts with concentrated nitric acid (HNO3) in the presence of sulfuric acid (H2SO4), a mixture of products is formed, including picric acid (2,4,6-trinitrophenol) and water. This reaction is known as nitration of phenol and is used to synthesize picric acid, which is a yellow, explosive compound.
Why h2so4 is necessary in preparation of nitrobenzene?
H2SO4 is necessary in the preparation of nitrobenzene because it acts as a catalyst in the nitration reaction. It helps in activating the nitric acid to facilitate the nitration of benzene to form nitrobenzene. Additionally, H2SO4 helps in maintaining the acidic conditions required for the reaction to proceed efficiently.
How do you balance S HNO3 yields H2SO4 NO2 H2O?
This reaction is:S + 6 HNO3 = H2SO4 + 2 H2O + 6 NO2
What is reaction of nonmetals with acids?
When dilute nitric acid (HNO3) reacts with non metals (excluding H2, C, N2 and O2) it forms acid from that non metal. For example, if HNO3 reacts with sulfur (S) it gives nitric oxide, water and sulfuric acid (H2SO4). It only reacts with carbon to form carbon dioxide (CO2) instead of its acid. Some more examples: HNO3 + P --> H3PO4 + NO + H2O HNO3 + S --> H2SO4 + NO + H2O HNO3 + Se --> H2SeO3 + NO + H2O HNO3 + C --> CO2 + NO + H2O HNO3 + S --> H2SO4 + NO + H2O
If you are given 3 mineral acids such as concentrated Hcl concentrated Hno3 concentrated H2So4 How will you distinguish between them without performing any tests?
Hey its a very good conceptual question.... As per my level of knowledge, HCl is too volatile as compared to other two. HCl will come up with fumes continuously while its in open container. HNO3 gives characteristic smell of nitrates in open and give slight change in its colour towards pale yellow. H2SO4 among these three is most denser and that is why comprises maximum weight when equal volume of all three are compared and fumes are least. I hope this answer fulfils what you wanted.

What are six strong acids?

What is the name of the gas results in mixing hno3 and h3nso3?
When you mix Nitric Acid HNO3 with Sulphamic Acid H3NSO3 you will get NITROUS OXIDE N2O , Sulphuric Acid H2SO4 and Water H2O
What type of reaction is na2so4 plus HNO3?
NaNO3 + H2SO4
Why H2So4 is used in acidification of KMno4 solution not HCl or HNo3?
H2SO4 is used in acidification of KMnO4 solution because it is a stronger acid compared to HCl or HNO3, which ensures complete dissociation of the acid and provides a higher concentration of H+ ions for the redox reaction to occur efficiently. Additionally, H2SO4 is not easily oxidized by KMnO4, unlike HCl or HNO3 which could interfere with the redox reaction.
