Why is KI a catalyst for H202 decomposition but KBr and KCl aren't?
The mechanism of catalysis involves the I- ion only. The mechanism is: H2O2 + I- --> IO- + H2O H2O2 + IO- --> I- H2O O2 Second step regenerates the I- ion (thus acts as a catalyst). This reaction is first order wrt to both H2O2 and I-. Notably exothermic reaction. Must be in a medium which allows formation of I-, ie dissociation of KI. Water is a wonderful example.
What type of reation is 2NaCO3 2Na 2CO2 O2?
NaCl-----------------Na+ + Cl-is a dissociation reaction.
Is the heating of calcium carbonate a synthesis reaction?
Heating of calcium carbonate (and the transformation in calcium oxide and carbon dioxide) is not a synthesis; it is a reaction of thermal dissociation.
What happens when copper ion solution is combined with lithium ion solution?
It starts a reaction
What is a reaction where free element element takes the place f an element in a compound?
A reaction when a free element or ion takes the place of and element or ion in a compound is called a single replacement reaction
Why nitration reaction is not used for synthesis of p-nitroaniline?
due to we do this reaction in acidic condition here the formation of anilinium ion takesplace which is deactivating group then if we add nitration mixture substitution takes place at meta position means we don't get 4-nitroaniline
What is an anilinium?
An anilinium is the cation formed by protonating the amino group of aniline.
What is the dissociation equation for iron sulfide in water?
The reaction is:FeS2 + H2O + 3,5 O2 --------------- FeSO4 + H2SO4It is not a dissociation reaction.
Why aniline is weaker base than methylamine?
Since tha pka of the aniline ion is equal to 4.6, the anilinium ion is a stronger acid than the methylaminium ion, and aniline (c6h5nh2) is a weaker base than methylamine (ch3nh2).
Name two ions that are the products of the dissociation of water?
Another way to describe the dissociation of water is as follows where two water molecules form a hydronium ion (essentially a water molecule with a proton attached) and a hydroxide ion
What type of ion is found in solution when an acid is formed?
That depends on the reaction. If you just want the general reaction you can consider the dissociation of water: H2O ------> H+ (acid) and OH- (base) or H2O + H2O --------> H3O+ (acid) and OH- (base)
What is the reaction of Na Cl -- Na-Cl?
NaCl-----------------Na+ + Cl-is a dissociation reaction.
How do you make a sodium chloride ion?
Sodium chloride is a compound not an ion; after dissociation of NaCl ions are obtained: Na+ and Cl-.
Do sodium ion reacts with water?
Sodium ion exist in water as the product of a dissociation; sodium (metal) react violently with water
Why is only one arrow required for the dissociation of a strong acid?
because the reaction of dissociation is At any one time virtually 100%
What happens of the equilibrium of a weak acid dissociation reaction were upset?
The reaction would shift to balance the change
What would happen if the equilibrium of a weak dissociation reaction were upset?
The reaction would shift to balance the change
