Zinc- nickel single flow batteries with improved cycling stability by eliminating zinc accumulation on the negative electrode. Electrochim. Acta 145, 109–115. doi: <u>Zinc accumulation is recognized as one of the most critical issues that affect the cycle life of zinc-nickel single flow batteries (ZNBs).</u>
<h3>What is
Zinc- nickel?</h3>
High performance zinc-nickel coatings provide superior corrosion resistance, especially for items used in challenging situations.
A special composition that will corrode less quickly than zinc alone is produced by alloying nickel and zinc. This alloy coating, with a composition of roughly 10-15% nickel and the remaining zinc, can offer up to ten times the protection of traditional zinc plating.
Due to considerations including extended product warranties, longer life cycle requirements, stricter safety regulations, and decreased environmental effect, there is an increased demand for Zinc Nickel Large across sectors. Following applications commonly call for zinc-nickel:

Answer:
4) KNO₃ because is unsaturated.
Explanation:
The solubility of KCl in water at 20°C is 10.0g/100,0g and of KNO₃ is 30.0g/100.0g.
When you make a solution under these concentrations, the solutions will be saturated, higher concentrations gives heterogeneous solutions. Lowers concentrations gives homogeneous solutions.
As concentration of the solution made for the student is 20.0g / 100.0g:
If the solution is of KCl produce a heterogeneous solution because is oversaturated.
If the solution is of KNO₃ produce a homogenous solution because is unsaturated.
Thus, the solution is made of <em>4) KNO₃ because is unsaturated.</em>
