Is KF An Acid Or Base? What You Should Know! - ScienceWised

Is KF a weak acid? - BYJU

WebKF is made by the reaction of a strong base and weak acid, so we can say that there is a basic character present within the molecule. Rather it is a basic salt. The pH range of KF lies between 5.5 to 8. So, it is a very wide range. So, it’s difficult to say its acidity. Why and How KF is weak basic?
