... I found the concentration of urea to be 0.58g/100 cm3. Figure 2.2 clearly shows that as the concentration of urea increases, the volume of HCl required for neutralisation also increases. This is to be expected as there are more moles of urea being hydrolysed, which would mean more HCl would be requi ...
