Is detergent solution is a acid or base or neutral?

Answer 1

detergent solution may be less than pH 7 like most anionic surfactants or alkaline like cationic OR amphteric(balanced pH in solution.)

Answer 2

Detergent solutions can be either acidic, basic, or neutral, depending on their ingredients. Some detergents are formulated to be slightly basic (pH greater than 7) to enhance their cleaning ability. It ultimately depends on the specific formulation of the detergent product.
