pH of a solution is 4.0. What should be the change in the hydrogen ion concentration of the solution if it's pH is to increased to 5.0 *
halved
doubled
increases by 10 times
decreases to 1/10 of its original concentration
Answers
Answer:
Hydrogen ion concentration will decrease if pH is increased.
It will increase it it's halved.
Definitely increase if it's doubled.
Increase but it's not possible to get 40 reading in pH.
Increase very much if pH becomes 1/10th.
Explanation:
The pH scale
The pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H+ ion concentration. The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. acidic solution has a high concentration of hydrogen ion greater than that of pure water.
A basic solution has a low H+ concentration, less than that of pure water.
