POSSIBLE ANSWER: nickel (Ni)
EXPLANATION: all metals dissolve in water more or less and there is an equilibrium point at which the dissolving rate and the condensing rate are the same. If the solution already has enough nickel ions (in other words it is a saturated solution), then the solid nickel you put in will not dissolve.

The aqueous solution of zinc sulphate is?
The aqueous solution of zinc sulphate is a clear, colorless liquid that is soluble in water. It is often used in various industrial applications such as in the production of agriculture fertilizers and in the electrolytic plating of zinc onto other metals.
What is the pH of a dime or quarter or penny?
The pH of metals like dime, quarter, and penny is generally neutral or close to neutral, around 5.5 to 7.0. Metals typically do not have a measurable pH value since pH is a measure of the acidity or alkalinity of an aqueous solution.
A substance that does not dissolve in a solvent is said to be what in that solvent?
- Sand does not dissolve in water- Plastic does not dissolve in water- metals do not dissolve in water
Which metal can easily dissolve solid gold at ordinary room temperature?
Mercury
Why amonia solution of alkali metals are blue in clour?
The blue color of alkali metal solutions is due to the formation of solvated electrons. When alkali metals dissolve in ammonia, they lose an electron to form free electrons that react with the solvent (ammonia) to create a blue color. This phenomenon is known as the formation of solvated electrons and is responsible for the blue color of the solution.
Which metal could not be used for electroplating by using an aqueous solution?
Silver
What is hydrometallurgy?
The use of aqueous solutions for the recovery of metals. Example: Leaching of copper oxide ores using a sulphuric acid solutions (or solution containing sulphuric acid). The Copper can then be recovered from solution using solvent extraction and electrowinning.
What color are main group metals as solids and in solution?
Main group metals are generally a silvery color and caesium has a goldy tinge. In aqueous solution they are all colorless. (In this respect they can be contrasted to the metals copper, gold which are very colored in the metallic state- and with transition metals in aqueous solution which can often be colored where they have have d electrons that can be excited by light leading to absorption of some frequancies giving a color. Alkali metals (sodium, potassium etc in group 1) dissolve in liquid ammonia to give an intense bright blue color- due to ionisation and relase of an electron into solution.
How does pH affect metals?
A solution with a low pH (an acid) can dissolve certain metals.
A solid solution containing different metals?
a pan or silver
Is a solid solid solution containing two metals a acid?
No, a solid solution containing two metals is not an acid. Acids are substances that can donate protons (H+) when dissolved in water, whereas a solid solution of metals is a mixture of two or more metals that are uniformly distributed at the atomic level within a solid matrix.
How do you know if a solution is aqueous?
Difference Between Liquid and Aqueous• Liquid is a state of matter, while aqueous is a special type of liquid formed by dissolving a compound in water• All aqueous solutions are liquids, but not all liquids are aqueous solutionsPlease see related link
A solid solution containing different metals and sometimes non metallic substances?
Alloy
What are acid and alkali leaching?
Acid leaching refers to a process in which an acid solution is used to extract metals from ores or materials. Alkali leaching, on the other hand, involves using alkaline solutions for the same purpose. Both methods are common in hydrometallurgical processes for recovering metals from their ores.
The aqueous solution of zinc sulphate is?
The aqueous solution of zinc sulphate is a clear, colorless liquid that is soluble in water. It is often used in various industrial applications such as in the production of agriculture fertilizers and in the electrolytic plating of zinc onto other metals.
What properties do acids exhibit when they are in an aqueous solution?
Acids in an aqueous solution exhibit properties such as turning blue litmus paper red, reacting with metals to produce hydrogen gas, and having a sour taste. They also conduct electricity and have a pH below 7.
What is the hydro metallurgy process of extracting copper ore?
Hydrometallurgy is a process that uses aqueous solutions to extract metals from ores. In the case of copper, the ore is typically crushed and then leached with sulfuric acid to dissolve the copper into solution. The copper is then extracted from the solution using techniques such as solvent extraction or electrowinning to obtain pure copper metal.
