Realiza los siguientes ejercicios y escribe si se trata una sustancia ácida o alcalina Hallar el pH de una solución cuya concentración de iones [OH-] es de 3.5x10-3
1- Calcular el pH de una solución de ácido acético, que contiene una concentración en H3O+= 3x10-4

You encounter a solution that is acidic and you decide to test it by adding a small amount of a strong acid. the ph lowers slightly but is approximately unchanged, and still remains acidic. what can you say about the solution? a. it is a buffer solution. b. it is not a buffer solution it is a strong acid solution. d. the solution has been neutralized. e. the solution has excess acid present

How does concentration affect reaction rate

Amixture that has two or more substances that are spread out evenly is called a. compound b. heterogeneous c. substance d. homogeneous
