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. WebA pH scale ranges from 0 to 14. A pH that is lower than 7 is acidic meaning that they contain hydrogen ions (H +), the more the H + ions the stronger the acid. And pH reading of 0 to 6 …
