this is buffer system consisted of a weak base and its conjugated base. NH4OH is the weak acid and the NH4Cl is the conjugated base. when an acid or a base is added in small amount the change of the pH of this solution is neglegible hence we tells that this shows a resistivity when adding an acid or a base .when an acid is added OH ions reacts and form H2O and NH4OH dissociates and give the OH ions to the solution .When an base is added NH+ ions react with OH ions added and form NH4OH which dissociates weakly to NH+ ions and OH- ions .

Why is NH3-NH4CL buffer preferred in edta titration for determination of mg?

The NH3-NH4Cl buffer is preferred in EDTA titration for the determination of magnesium because it helps maintain a relatively constant pH (around 10), which is necessary for the formation of stable complexes between EDTA and magnesium ions. The NH4Cl helps prevent the precipitation of magnesium hydroxide, which could interfere with the titration.


What is the balanced chemical equation when NH4Cl is heated?

When NH4Cl is heated, it decomposes into NH3 gas and HCl gas. The balanced chemical equation for this reaction is: NH4Cl(s) -> NH3(g) + HCl(g).

What is the pH of a solution that is 0.13 M in NH3 and 0.17 M in NH4Cl?

This represent a buffer of a weak base (NH3) and the conjugate acid (NH4+), so one can use a form of the Henderson Hasselbalch equation like pOH = pKb + log [conj.acid][base]. The pKb for NH3 is 9.25, so pH = 9.25 + log [0.17]/[0.13] = 9.25 + 0.12 = 9.37 = pH

What is the dissociation equation for NH4Cl?

Usually, ammonia in water solution is presented as NH3.H2O (sometimes NH4OH which is rather incorrect) then NH3.H2O + HCl = NH4Cl + H2O but also this reaction is correct NH3 + HCl = NH4Cl
