Acids and Bases - Wyzant Lessons
Bases neutralize acids in a neutralization reaction. The word – reaction is: Acid plus base makes water plus a salt. Where ‘Y’ is the anion of acid ‘HY,’ and ‘X’ is the cation of base. ‘XOH,’ and ‘XY’ is the salt in the product, the reaction is: HY + XOH ===> HOH + XY. Bases denature protein.
