Answer:
Explanation:
*Since the titration is between the strong acid HCl and the strong base Ca(OH)2, the pH at the equivalent point should be 7. On interpolation, we will obtain that 9.50mL and 9.82 mL of HCl is required to completely neutralized the given Ca(OH)2 solution.
*pH at the equivalence point =7
we know that pH + pOH = 14
Hence pOH= 14-7=7
pOH= -log(OH-)
The concentration of OH-= 10-pH= 1X10-7 M
One reason for the low solubility may be the higher reaction temperature, Another reason is the common ion effect.
Answer:
The correct answer to the following question is "TRUE".
Explanation:
- Hot spots become areas within the mantle of the planet whereby unusually warmer stones melt to form magma which grows through all the surface as well as melt through as well.
- This seems to be a region where even the water rises through deeper inside the earth as well as warms thru the surface just above, this occurs in locations that are more or less near and nothing like the boundary of the plate.
So that the given is the correct statement.
