lead sulfate
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
Balanced equation formed: H2SO4 + 2KBr ==> 2HBr + K2SO4
The product of acetone heating with concentrated H2SO4 is usually the formation of a ketone known as mesityl oxide through a dehydration reaction.
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.
The chemical equation for sulfur reacting with hot concentrated nitric acid is: S + 6HNO3 → H2SO4 + 6NO2 + 2H2O
When ethanol is heated in the presence of concentrated H2SO4, it undergoes dehydration to form ethylene gas. This reaction follows an elimination mechanism where a water molecule is eliminated from ethanol to produce ethylene.
The reaction is:C + 2 H2SO4 = CO2 + 2 SO2 + 2 H2O
Balanced equation formed: H2SO4 + 2KBr ==> 2HBr + K2SO4
The product of acetone heating with concentrated H2SO4 is usually the formation of a ketone known as mesityl oxide through a dehydration reaction.
H2SO4 is a highly concentrated acid.
The chemical reaction (a dehydration reaction) is:C12H22O11 + H2SO4 = 12 C + 11 H2O
a strong acid like HF, H2SO4...are stronger when they are concentrated, weaker acids are weak even they are concentrated

The chemical equation for sulfur reacting with hot concentrated nitric acid is: S + 6HNO3 → H2SO4 + 6NO2 + 2H2O
The reaction is:NaBr(s) + H2SO4(l) → HBr(g) + NaHSO4(s)
Sulfuric acid is a strong mineral acid with the chemical formula H2SO4. It is colorless, odorless, and highly corrosive in its concentrated form.
The first solution is more concentrated because it contains 6 moles of H2SO4 per one liter of solution. The second solution is less concentrated because it contains 0.1 moles of H2SO4 in one liter. In equal amounts of each example, the first would have more H2SO4.
