The equivalence point is reached when the titrant added neutralizes the titrand. It is thought that when a solution is neutral it would have a pH of 7. However, the combination of a weak acid and a strong...

PV=nRT V=0.8 dm³=0.8 x 10^-3 m³P= nRT/V R= 8.31 J K^-1mol^-1 T= 330 K n= mass/mr n = 15 g/ (2x35.5 g mol^-1) n = 0.212 mol P = (0.212 mol x 8....

When a reaction is in equilibrium, it means the rate of the forward reaction is equal to the rate of the backwards reaction. The concentrations of the reactants and products remain constant, but this does...

Metal + Acid --> Metal salt + H2 (g)E.g. Cu + HCl --> CuCl2 + H2

Answer= 0.144gWorking out:mol= conc x volume (in dm^3)mass = mol x RFFSo,mol = 0.18 x (20/1000) = 0.0036molMass= 0.036 x 40 = 0.144g
