A substance with a high [H ] would likely have which additional characteristics? a high [OHâ€"" ] and a high pOH a low [OHââ
viktelen [127]

The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.

The substance having high \rm [H] will have:

Option B. A low \rm [OH ^{-}] and a high \rm pOH

This characteristic can be explained as:

  • The concentrations of \rm [H^{+}] and \rm [OH ^{-}] are inversely dependent on each other so when the concentration of  raises then the concentration of \rm [OH ^{-}] drops and vice versa.

  • The pH of a solution or substance is calculated with the help of:

\rm  pH  = \rm - log  \rm [H^{+}]

From the formula, it can be deduced that when the concentration of \rm [H^{+}] is high then the pH has a low value and it means that the solution is acidic.

  • pH can also be written as:

\rm pH + pOH &= 14 \\\\\rm pOH &= 14 - pH

From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.

Therefore, when pOH is in high concentration then \rm [OH ^{-}] is low.

Are the following combinations allowed? If not, show two ways to correct them:
mafiozo [28]

The following combination of n=3 ; l=1 ; ml=-2 is not allowed. One way to correct this would be by changing the azimuthal quantum number, l and the other way would be to change the magnetic quantum number, m.

<h3>Is the following combination n=3; l=1; ml=-2 allowed or not.? If not, suggest two ways through which it can be corrected.</h3>

The following combination of n=3 ; l=1 ; ml=-2 is not allowed.

There are several rules that need to be followed for assigning electron quantum numbers. They are:

1. Principal quantum number should be 1 ≤ n

2. Azimuthal quantum number, 0 ≤ l ≤ n − 1

3. Magnetic quantum number, -l ≤ ml ≤ l

4. Spin quantum number as either -1/2 or +1/2

For n = 3,

l should be n - 1 or n - 2 or n - 3 = 2, 1, 0 respectively.

If we choose l = 1 then ml should be -1, 0 and +1

Therefore, one way to correct the combination would be to change the magnetic quantum number to -1

If we choose l = 2 then ml would be -2, -1, 0, +1, +2

Thus, another way to correct the combination is to choose the azimuthal quantum number as 2.

Thus, the following combination of n=3; l=1; ml=-2 is not allowed. One way to correct this would be by changing the azimuthal quantum number, l and the other way would be to change the magnetic quantum number, m.
