In order to neutralize a basic solution, you would need to add a solution with a pH higher than 7. A. True B. False C. I have no idea.
This statement is false. In order to neutralize a basic solution you would need to add a solution with a pH lower than 7.
The pH scale describes the hydrogen ion concentration, abbreviated [H+], of a solution. A solution that is neutral has a pH of 7. It has equal concentrations of H+ and OH- (hydroxide ion). A basic solution has a pH greater than 7 and it contains more OH- ions than H+ ions. An acidic solution has a pH less than 7 and contains more H+ ions than OH- ions.
H+ ions and OH- ions neutralize each other by forming water:
`H^+ + OH^(-) -> H_2O`
In order to neutralize a basic solution you would need to add a solution with an excess of H+ ions to react with the excess of OH- ions. This would be an acidic solution, one with a pH below 7. The amount needed to neutralize the solution would depend on the volume and concentration of the basic solution and the concentration of the acidic solution.
The attached video explains acids, bases and pH.
This statement is False.
The pH scale ranges from 0 to 14 with 7 being neutral. Solutions that are basic, or alkaline, have a pH that is greater than 7. Solutions that are acidic have a pH that is less than 7. The further you move away from neutrality, the more acidic or basic a solution becomes.
To neutralize a basic solution, you have to lower the pH number to 7. To do this, you have to add a solution that has a pH that is less than 7, or an acid. Adding an acid to a base is called a Neutralization reaction. When you neutralize the base with the acid, the result will be water plus a salt.
If you use an acid that is too strong, then the result will be an acidic solution. If you use an acid that is too weak, then the solution will still be basic, just less basic.
