if its complete dissociation, then the products would be a salt and water, which means the pH is 7 or neutral. OMG, if the pH is currently 4 then [H+] = 1.0 e-4 M (pH = -log[H+]) if you add 0.003 moles then 1.0e-4 M +.003 M = .0031 M (Since the strong acid HCL completely dissociates in aq solution) pH = -log [.0031M] = 2.51
The chemical formula of sodium chloride is NaCl; in water solution, after dissociation, the ions Na+ and Cl- exist.

look at Calculate_the_boiling_point_elevation_of_an_aqueous_solution_of_0.0500_m_CaCl2_Assume_complete_dissociationvery similar questionanswer is 1.64 lower than the originial freezing pointif the freezing point is 0 for example the freezing point depression is -1.64
The water molecules surround the negative ions and positive ions and pull them away into the solution. This process is called dissociation
Hydroiodic Acid. It is a strong acid (100% dissociation).
The mole fraction of HCl in 20 percent aqueous solution is 0.21.
The chemical formula of sodium chloride is NaCl; in water solution, after dissociation, the ions Na+ and Cl- exist.
For example the dissociation of HNO3 in water prduce the ion H+.
IT is a BASE because it falls under the base properties catagory
This solution is called water solution or aqueous solution.
'An Aqueous' solution. NB The word 'aqueous' comes from Latin ; 'aqua' meaning 'water'.
Ka = ([H+][A-])/[HA]) Let concentration of dissociated acrylic acid be x. 0.000056 = (x2)/(0.10 - x) Rearrange: 0.0000056 - 0.000056x - x2 = 0 x = 0.002339 Therefore: [H+] = 0.002339 M pH = -log[H+] = 2.63 Percent dissociation: 0.002339/0.10 = 0.02339 = 2.34 %
Aqueous solutions are solutions in which water is the solvent. Anything that dissolves in water forms an aqueous solution.
