Answer: The molarity of the initial concentrated solution is 0.450 M
Explanation:
According to the dilution law,
where,
= Molarity of concentrated KOH solution = ?
= volume of concentrated KOH solution = 175 ml
= concentration of diluted KOH solution= 0.315 M
= volume of diluted KOH solution= 250 ml
Putting in the values, we get:
Thus the molarity of the initial concentrated solution is 0.450 M
In this reaction, Copper is the element being oxidized because it is losing electrons. It starts with a neutral charge (0) and ends up with a 6+ charge. Because its charge is increasing, it is being oxidized (losing electrons).
False, because physical change does not involve the formation of substances. An example of physical change is change of state e.g water freezing .It is still water if you were to melt it.
