If I have 60 g of NH4Cl and I place it in 100 g of water at 60 degrees Celsius, will all of it, some of it, or none of it dissolve?
O all
O some
O none

Calculate the ph at the equivalence point for the titration of a solution containing 150.0 mg of ethylamine (c2h5nh2) with 0.1000 m hcl solution. the volume of the solution at the equivalence point is 250.0 ml. kb forethylamine is 4.7 × 10−4 .
