Answer:
The metal that spontaneously reacts with NiCl₂ is Zn solid.
Explanation:
Is this a multiple choice question? if it is you can show me the answers and then I can figure it out.
Answer:
B. False
Explanation:
Solution -
A solution is referred to be a uniform mixture of various components , where the components are classified as solute and solvent .
The components can easily be segregated on the basics of the amount of the component , i.e. ,
- The component with higher concentration is referred to as the solvent.
And ,
- The component with lower concentration is referred to as the solute .
For example ,
In the solution of sugar and water , where 1 tablespoon of sugar is dissolved in 100 mL of water ,
- the concentration of sugar is less , and hence , is referred to as the solute ,
and ,
- the concentration of water is more , and hence, is referred to as the solvent.
The required volume of 0.10M NaOH solution that student will add is 20 mL.
<h3>How do we calculate the volume?</h3>
Volume of any solution which is required to prepare buffer will be calculated by using the below equation as:
M₁V₁ = M₂V₂, where
- M₁ & V₁ are the molarity and volume of NaOH solution.
- M₂ & V₂ are the molarity and volume of HF solution.
On putting values, we get
V₁ = (0.1)(20) / (0.1) = 20mL
Hence required volume of NaOH solution is 20mL.
