What happen when H3PO4 is used instead of H2SO4 in preparation of dry NH3?
my nan is hot
What is the reaction between potassium permanganate and sulphuric acid and oxalic acid?
Potassium Permanganate (KMnO4) reacts with Sulphuric acid (H2SO4) to produce Manganese Heptoxide (MnO7), water (H20) and Potassium Hydrogen Sulphate (KHSO4)2. The reactive species produced is Manganese Heptoxide (which is a very powerful oxidiser). The Manganese Heptoxide will oxidise the Oxalic acid (COOH)2 to Carbon dioxide (CO2).
What happens when zinc dust is added to an acidified solution of potassium permanganate?
KMno4 is reduced to Mn^2+ Salt and the pink colour is discharged by the nascent hydrogen produced when zinc reacts with h2so4
How to get the balance equation for a redox reaction of oxalic acid plus potassium permanganate?
This redox reaction also requires an acid as H2SO4 , the overall reaction is.... 5H2C2O4 + 2KMnO4 + 3H2SO4 = K2SO4 + 2MnSO4 + 10CO2 +8H2O
Why KMnO4 titration's are carried out only in the presence of dilute H2SO4?
The permanganate ion, MnO4- purple in colour. The sulfuric acid is added to create acidic conditions. In acidic conditions, the MnO4- gets reduced to Mn2+ which is colourless. Therefore, judging by the colour change, we can figure out how much of the potassium permanganate has been used.

What is the word equation of potassium hydroxide and sulphuric acid?
If is K2O (potassium oxide) it would be: K2O+H2SO4=K2SO4+H2O It could also form potassium bisulfate: K2O + 2 H2SO4 = 2 KHSO4 + H2O But I'm not sure if you are referring to potassium peroxide (K2O2) or superoxide (KO2)
Why h2so4 is necessary in preparation of nitrobenzene?
H2SO4 is needed to first react with HNO3 to give NO2
Why the conc h2so4 cant be used in preparation oh h2s?
h2so4 being good oxidising agent oxidises the h2s to h2o and free sulphur.so conc h2so4 cant be used in preparation of h2s gas
What is the formula for potassium hydroxide plus sulfuric acid?
2koh+h2so4 --> 2h2o + K2SO4or1koh+h2so4 --> h2o + KHSO4
What does H2SO4 plus KOH yield?
Water and potassium sulfate
Sodium Peroxoborate reacts with sulfuric acid and potassium permanganate to give what products?
2MnO4- + 5H2O2 + 6H+ → 2Mn2+ + 5O2 + 8H2O Permanganate is added to H2SO4 + H2O2 and is reduced because it is a better oxidising agent that H2O2 the purple MnO4 ion is used up and the solution fades almost to clear if the mix is right
Write an acid-base reaction for sulfuric acid with potassium hydroxide?
2KOH + H2SO4 --> K2SO4 + 2H2O2KOH(aq) + H2SO4(aq) --> K2SO4(aq) + 2H2O(l)
