If a base is added to water, the pH will
increase, decrease, stay the same, or increase sometimes and decrease sometimes.
I have asked several friends and the two answers I get is increase from 3 of them and stay the same from 2 of them. I am confused.
And so are your friends, at least half of them, anyway. :-)).
pH is a scale for acidity (or basicity).
It runs from 0 to 14 for most solutions.
7 is neutral.
<7 is acid.
>7 is basic.
Pure water at 25o C is neutral. Adding a base will make the pH greater than 7 and that will be basic.
if a base is added to water it becomes a base just more translucent so it would be >7.
To confirm the correct answer, we need to understand the basic properties of a base. A base is a substance that can accept or take up hydrogen ions (H+) in a chemical reaction. When a base is added to water, it will increase the concentration of hydroxide ions (OH-) in the solution.
Now, let's consider the possible answers:
1. Increase: This is the correct answer. Adding a base will increase the concentration of hydroxide ions in the water, making it more basic and causing the pH to rise above 7. Therefore, the pH will increase.
2. Decrease: This is incorrect. Adding a base will not decrease the pH of the water.
3. Stay the same: This is incorrect. Adding a base will definitely change the pH of the water, as it increases the concentration of hydroxide ions.
4. Increase sometimes and decrease sometimes: This is incorrect as well. Adding a base will always increase the pH, not decrease it.
So, based on the definitions and properties of bases, the correct answer is that the pH will increase when a base is added to water.
