    yhi question hain sir pH nikalna JB dono ko mix krenfe

    eduncle-logo-app

    As weak acid is there so ph is generally calculate from the H+ coming from the strong acid HCL

    eduncle-logo-app

    So the ph of this mixture nearly comes to 3 as the ph of 0.3 M hcl is 3.

    In exam you can simply check this by option only by calculating the ph of strong acid and mark the answer which comes near to that ph

    eduncle-logo-app

    There is one direct formula of calculating the ph of mixture of strong acid and weak acid
