John has a solution with a pH of 12.21. what is the hydrogen ion concentration of this solution? ​

Chemistry

Georgia [21]3 years ago
5 0

Answer:

  1. In this way, ph is determined by hydrogen ion concentration . In the case of neutral solution [H+] =10-7 which we call a ph of 7. This means, for example, that a hydrogen-ion concentration of a solution with a ph of 4 is 10-4 mol/l, meaning it contains 0.0001 mole of hydrogen ion in a solution of 1 liter.

How does hydrogen bonding affect water molecules
ruslelena [56]
Since the oxygen likes to hog all the electrons, it gives the hydrogen molecules a slight positive charge and the itself a slightly negative charge.
Positive attracts negative, so there is some sort of attraction between water molecules, though a weak one.

In the reaction, 2 Al (s) + 6HCL (aq) --> 2ALCL3 (aq) + 3 H2 (g), 2.00 g of Al will react with how many milliliters of 0.500
san4es73 [151]

Answer:

The volume of HCl required is V = 420 mL

Explanation:

From the question we are told that

    The chemical equation for this reaction is

             2 Al _{(s)} + 6 HCl _{(aq)} -----> 2 Al Cl_{3} _{(aq)} + 3 H_2 _{(g)}

    The mass of Al  is m__{Al}} = 2.00g

    The concentration of HCl is C__{HCl}} = 0.500M

The number of moles of Al given is n__{Al}} = \frac{mass \ of  Al}{Molar \ mass \ of \ Al}

   The molar mass of Al is  M = 27 g/mol

       So

               n__{Al} = \frac{2}{27}

               n__{Al} =  \ 0.07 \ moles

From the balanced equation

           2 moles of  Al  reacts  with  6 moles of  HCl

So        0.07 moles of Al will react with x

  Therefore

                x = \frac{0.07 *6}{2}

                x = 0.21 \ moles

Now the volume of HCl can be obtained as

           Volume(V) = \frac{moles}{concentration }

 So       V = \frac{0.21}{0.500}

             V = 420 mL
