If something is acidic, it will: be able to donate H+ions taste sour have a pH less than 7 If something is basic (also sometimes called alkali or alkaline), it will: not be able to donate H+ions easily, and in fact they’ll usually absorb H+ions or donate hydroxide ions (OH–)...
When a base is added to an acid (or an acid added to a base), the solution moves toward the middle of the pH scale as it is partially or fully neutralized. Using Bases to Clean Acids Most of the substances that soil our homes and laundry are acidic when measured on the pH scale, ...
