A NaOH(aq) solution with a pH value of 13 is used to determine the molarity of a HCl(aq) solution. A 10.0-mL sample of the HCl(a
erica [24]

Answer:

pH of the H⁺(aq) is 0

Explanation:

It is possible to know the  concentration of a HCl(aq) solution by titration with a solution of NaOH(aq) with known concentration. The reaction is:

HCl(aq) +  NaOH(aq) → H₂O(l) + NaCl(aq)

The added moles of NaOH are equal to moles of HCl and as you know volume of HCl added you will obtain concentration of HCl.

Now, a solution of H⁺(aq) with a concentration 10 times greater than original NaOH(aq) solution -0.100M-, has a concentration of 1.00M H⁺(aq), the pH of this solution is:

pH = -log (1.00M H⁺(aq) = 0

That means <em>pH of the H⁺(aq) is 0</em>

What causes element name to change
amm1812
For example, iron plus oxygen can become ferric oxide. Both elements change their names. The change is used to indicate the kind of bonding process that is taking place. When iron and oxygen become ferric oxide, the iron has lost electrons and the oxygen has gained the electrons that iron lost. <span>
