${\huge{\red{Answer}}}$

Bases are substances that slippery to touch when in aqueous form. They taste bitter and change the color of red litmus paper to blue. Bases also dissociate in the water like acids, but instead of producing H+, they produce OH- i.e. hydroxyl ion. The word “acid” is derived from the Latin word “acid” which means sour.
