Answer:
60.0mL of the diluted solution are needed
6.00mL of the 1.00M NaOH stock solution is the minimum volume needed to prepare the diluted solution.
Explanation:
As in each titration we need to use 20.0mL of the diluted 0.100M solution. As there are 3 titration, the volume must be:
3 * 20.0mL = 60.0mL of the diluted solution are needed
Now, to prepare a 0.100M NaOH solution from a 1.00M NaOH stock solution the dilution must be of:
1.00M / 0.100M = 10 times must be diluted the solution.
As we need at least 60.0mL, the minimum volume of the stock solution must be:
60.0mL / 10 times =
<h3>6.00mL of the 1.00M NaOH stock solution is the minimum volume needed to prepare the diluted solution.</h3>
The chemical equations representing the reaction between the given combinations are:
1. .This reaction is a precipitation reaction as one of the product formed, CaSO is a solid.
2. In this reaction all the products are aqueous or soluble in water.
3.. Both the products of this reaction are soluble in water.
Hence, the correct option would be 1. CaS +
