Answer: Thomson's showed that atoms contain smaller particles, so it was important to change the theory of daltons. Rutherford found that most of of an atom is hollow and in the middle of an atom is concentrated energy. This contributed to the revision of the plum pudding model.
The first step is calculating the number of HCl moles. The molar mass of HCl is AH+ACl which is 1+35,5=36,5 g/mole. The formula for the pH is -lg[H+] where [H+] is the molar concentration of protons in the solution. To find the molar concentration we need to divide the number of moles by the volume(L).
We get the number of moles by dividing the mass given in the problem to the molar mass of the compound.1.825/36.5=0.05 moles of HCl so 0.05 moles of
H+.Molarity=n/V=0.05/0.25=0.2moles/liter.The pH is -lg0.2=2.321.

Explanation:
For balancing acidic solutions, we would need to add H+ ions to the correct side of the equation to balance the total number of atoms and the overall charge.
