Answer:
Mg(s) + 2HCl (aq) ------> H2 (g) + MgCl2 (s)
Explanation:
Mg(s) + 2HCl (aq) ------> H2 (g) + MgCl2 (s)
before Mg -1, H -2,Cl -2
after Mg -1, H2, Cl - 2
The Hydrogen Ion
Concentration determines the pH at endpoint.
The concentration of H in
the solution and how close to 1 is the concentration. 7 is neutral and 1
is acidic. pOH is also the base concentration in the solution so this is the
measurement of the amount of base in the solution.
