Answer:
not direct variation
Step-by-step explanation:
The equation for x and y in direct variation is
y = kx ← k is the constant of variation
y =
is not in this form, thus not direct variation.
The equation for x and y varying inversely is
y =
← k is the constant of variation
y =
is in this form and represents inverse variation
Answer:
The concentration of hydrogen ions in moles per liter (M) is 
Step-by-step explanation:
As we know
The hydrogen ion concentration of any solution at pH is given by

Substituting the given values in above equation, we get -
mol/l
The concentration of hydrogen ions in moles per liter (M) is
