Question

Indicati caracterul acido bazic al urmatoarelor solutii si argumentati: a) Solutia care are pH=1 ...
b) Solutia care are pH=12
c) Solutia care are [H3O+}= 10(-4)mol/L
d)Solutia care are [HO-]= 10(-4) mol/L

Answer 1

pH=1---> SOL. ACIDA

             SOL.BAZICA

pH=-log[H3O⁺]=4......SOL.ACIDA

[H3O]⁺= 10⁻¹⁴/10⁻⁴= 10⁻¹⁰-----> pH=10.....SOL.BAZICA
