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!.
Nothing - lead is the most recommended material for handling hot dilute sulphuric acid. Concentrated acid is a little different.
The lead in the lead acetate will react with Hydrogen sulfide and Lead sulphate will be formed which is black in colour.
nothing
The solution gets hot
Nothing.
Concentrated sulfuric acid strips the hydrogen and oxygen from sugar (sucrose) as water. Carbon is left. C12H22O11 + H2SO4 --> 12C + H2SO4. 11H2O
nothing happens
sodium acetate and water are formed.
The solution gets hot
copper sulphate and hydrogen is released.
it bubbles

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.
If it is added to a solution of dilute sulfuric acid, it will react slowly liberating hydrogen gas. With concentrated acid, iron will undergo a series of red-ox reactions.
