Question

Why should we use the solution of substance for acid base test?​

Answer 1

Answer:

➡➡It is usually used in either paper or solution form. Electronic pH meters: they can provide a very accurate pH reading, track pH changes and plot pH curves but are usually very expensive. Chemical tests: certain chemicals, such as acidic/basic oxides, will react with a basic and acidic solution respectively.
