Ph of nh4cl
WebWhat is the pH of a solution that is 0.036 M in NH4Cl at 25 °C? Question: NH3 is a weak base ( 𝐾b=1.8×10−5 ) and so the salt NH4Cl acts as a weak acid. NH3 is a weak base ( 𝐾b=1.8×10−5 ) and so the salt NH4Cl acts as a weak acid. WebThe reaction is HCl→H ++Cl −. ∙ So, it is clear that ammonium chloride is made of a weak base and strong acid. So, the solution is slightly acidic. Acidic solution means the pH is …
