Chemist Johannes Bronsted and scientist Thomas Lowry proposed that an acid should be defined as a substance that can donate a proton, while a base is any substance that can accept protons. American chemist G.N. Lewis proposed a different theory. Learn about three popular scientific definitions of...

The alkalinity of amino groups will undergo an acid-base neutralization reaction with HCl. How do we verify the reaction between these two substances? Let’s learn some common experiments for verifying the ethyl 4 aminobenzoate and HCl reaction. Experiments to Verify the Ethyl 4 Aminobenzoate and ...
The results indicate that the contamination of silty clay soil with HCl acid caused a reduction in strength and an increase in the compression index and coefficient of consolidation; the more significant change in compressibility and strength was seen when the acid solution became more acidic. ...
Oxytetracycline is an acid-base amphoteric substance, which can be combined with acid or base to form salts. It dissolves very little in water and is easily soluble in dilute alkali and dilute acid. Oxytetracycline salt is easily damaged and ineffective in alkaline aqueous solution, and is more...
