Explanation:
Basically, the hydroxonium ions, H3O+ are responsible for the acidity of a solution and the hydroxide ions, OH- are responsible for the basicity of a solution.
In an acid solution;
The concentration of the hydroxonium ions is greater than that of the hydroxide ions.
In a basic solution;
The concentration of the hydroxide ions is greater than that of the hydroxonium ions.
Answer: pOH = 3.13
Ba(OH)2 is a very basic substance. The general formula for pOH is - log(OH)
Barium Hydroxide produces 2 moles of OH for every mole of Ba(OH)2 present in the solution.
0.00037 M = 3.7 * 10^-4 Ba(OH)2 will produce 2 *0.00037 M of OH-
OH- = 2* 0.00037 = 0.00074
pOH = - log(0.00074) = 3.13
Answer:
17.5% es la transmitancia de la solución problema
Explanation:
Basados en la ley de Beer que dice que:
La transmitancia de una solución es inversamente proporcional a su concentración.
Podemos hallar la transmitancia de una concentración problema sabiendo la concentración de una solución y su transmitancia:
Si una solución 0.0150M tiene una transmitancia de 35%
Y ahora la solución duplica su concentración, su transmitancia se disminuirá en la mitad, esto es:
35% / 2 =
<h3>17.5% es la transmitancia de la solución problema</h3>
