why hno3 is not used in titration?

The acid used in this titration is dilute sulphuric acid. Nitric acid is not used as it is itself an oxidising agent and hydrochloric acid is usually avoided because it reacts with KMnO4 according to the equation given below to produce chlorine and chlorine which is also an oxidising agent in the aqueous solution.

The hydrated sodium salt of EDTA, Na2H2Y·2H2O, cannot be used as a primary standard for titrations due to uncertainties in the water content. ... This leads one to calculate the average molar mass of the reagent and its water content, allowing to use it to prepare EDTA standard solutions.

there is no way you can balance this.. mathematically its impossible to satisfy this by any whole number.. You wil realize it when you write set of linear equations for N,O,H species.. ... For whatever integer n you place on the left side, you need 2n NH3 and 2n HO.

During the course of the titration, the titrant (NaOH) is added slowly to the unknown solution. ... After the equivalence point, there will be an excess of NaOH and the solution will be basic. An acid-base indicator can be used to help identify when the change from acidic to basic occurs.

Because NH3 is an excellent leaving group - even better than H20. Another way to think about it is that good leaving groups are weak Lewis bases.

A titration curve can be used to illustrate this. Phenolphthalein is not suitable for ALL acid-base titrations. When titrating a strong acid with a strong base, the equivalence point is at a pH of 7.

The product, Na+, is inert and really stable. H2CO3 is a weak acid and does not completely dissociate. The product, HCO3-, is not stable and can react again with water to contribute to the pH. HCO3- will act as a base by plucking off the proton from H2O, and forming a basic solution.

KMnO4 acts as a self indicator because of its deep violet color which is highly visible to naked eye. When we titrate it, an apparent loss of this deep violet color occurs that indicates the end point of this titration.

HNO2 nitric acid is reacted with water it will act as other acids do, yes it will form hydronium ions.

Al(NO3)3 -> Al(OH)3 (weak base) and HNO3 (strong acid) -> Al +3 (strong acid) and NO3 - (weak base) -> Al(NO3)3 is acidic.

If you really mean NH2- as a leaving group, then you can rationalize this by noting that NH2- is somewhat basic (not super weak). Thus, they are somewhat reactive and make poor leaving groups. Ideally, you want your leaving group to be as unreactive as possible.

Both NH3 and H2O are amphoteric (they have H atoms that can be donated as H+ ions and thus act as acids and lone-pair electrons that can accept an H+ and thus act as bases). Thus, either NH3 or H2O can act as an acid or a base. When NH3 is mixed in H2O there is a competition for the proton.

2M HCl - The addition of acid is necessary to provide the acidic conditions required in the iodometric titration (see Equation 1). Use 4mL of the HCl solution in each titration. Starch solution - This will react with the aqueous iodine to form an intense blue color indicating that the endpoint has been reached.

The oxidation state of nitrogen in HNO3 is +5 and hence it can go to lower oxidation states but not higher so it acts only as an oxidizing agent where as in HNO2 oxidation state of nitrogen is +3 and hence it can go to higher or lower oxidation states so it can act both as an oxidizing and reducing agent.

(i) Concentrated HNO3 can be stored and transported in aluminium containers as it reacts with aluminium to form a thin protective oxide layer on the aluminium surface. This oxide layer renders aluminium passive.

HNO3 is an oxidizing AGENT because the N can be readily reduced. Nitric acid is an active oxidizing agent. ... Nitric acid is a strong oxidizing agent and the nascent oxygen produced on decomposition oxidizes hydrogen to water. This is the purpose why it does not release hydrogen when operated with metals.

Yes, Nitric Acid(HNO3) is a very strong oxidizing agent. ... Nitrogen in HNO3 is in +5 oxidation state which is the highest oxidation state of nitrogen that means nitrogen can not get oxidised but it can reduce to the lower oxidation state and oxidize oher molecules or atoms in a given redox reaction.
