What is the nameof the black substance produced when concentrated sulfuric acid is added to sugar?
Concentrated sulfuric acid strips the hydrogen and oxygen from sugar (sucrose) as water. Carbon is left. C12H22O11 + H2SO4 --> 12C + H2SO4. 11H2O
If zinc is first added to dilute sulfuric acid then concentrated sulfuric acid and acetic acid in which case will the fizzing be most and least?
The most fizzing will come from the concentrated sulfuric acid, then dilute sulfuric acid, then the acetic acid.The amount of fizzing is due to the concentration of H+ in the solution, and concentrated sulfuric acid has the most H+ in solution. The dilute sulfuric acid has less (because it is dilute) and the acetic acid solution has the least of all because it is a weak acid rather than a strong acid.See the Related Questions for more information.
What happens when you add sulfuric acid to water?
When sulfuric acid is added to water, it dissociates into hydrogen ions and sulfate ions. This process releases heat, so it is important to add the acid to water slowly and with stirring to prevent splashing or overheating. Additionally, diluting sulfuric acid with water helps to reduce the acidity and make it safer to handle.
What happens when lead acetate is added to concentrated sulfuric acid?
Pb2+ --> PbSO4(s)Concentrated sulfuric acid will 'burn' or 'carbon'ise acetate (CH3COO-) to Carbon black, CO2(g) and H2O(l) and some other intermediate products.Be very carefull! Very exothermic!You should never work with concentrated acids un-gided and unprotected!.
What happens when dilute sulfuric acid is added to zinc?
When dilute sulfuric acid is added to zinc, zinc reacts with sulfuric acid to form zinc sulfate, hydrogen gas, and water. The balanced chemical equation for this reaction is: Zn + H2SO4 -> ZnSO4 + H2.
What happens when copper is added to concentrated sulfuric acid and heated gently?
copper sulphate and hydrogen is released.

What happens to sulfuric acid added with zinc?
hydrogen gas evolved

What happens when a few drops of concentrated salt solution is added to pure water?
U evaporate it

What happens when zinc is added to dilute sulfuric acid in a test tube?
When zinc is added to dilute sulfuric acid in a test tube, a chemical reaction occurs where zinc reacts with sulfuric acid to form zinc sulfate and hydrogen gas. This reaction is a redox reaction where zinc is oxidized to zinc ions, while hydrogen ions in the sulfuric acid are reduced to form hydrogen gas. The production of hydrogen gas can be observed as bubbles forming in the test tube.
Is coconut flakes as good as coconut oil?
coconut oil has added things like coconut flakes
What happens when you add universal indicator to sulfuric acid?
It turns the universal indicator to scale 1
