Why cannot all minerals of a metal cannot be used for metal extraction?
In order to extract a metal from its mineral you need to have some solubility of that mineral, otherwise it will take too long. Let's say 2% solubility looks as a rational minimum
Write a general statement that describes the periodic trend in the solubility of alkaline earth metal compounds?
The solubility of alkaline earth metal compounds generally increases down the group in the periodic table. This trend is particularly evident for hydroxides and sulfates, where the solubility of hydroxides increases from beryllium to barium, while sulfates show a decrease in solubility from magnesium to barium. The increase in ionic size and decrease in lattice energy as one moves down the group contribute to this trend. Overall, this results in greater solubility for heavier alkaline earth metals compared to their lighter counterparts.
Which metal sulphide is soluble in water?
The metal sulfide that is notably soluble in water is zinc sulfide (ZnS) under specific conditions, particularly when it forms complex ions. However, most metal sulfides are generally insoluble in water. Another example is copper(I) sulfide (Cu2S), which can show some solubility in acidic solutions. Overall, the solubility of metal sulfides can vary significantly based on pH and the presence of complexing agents.
What is the reaction of metallic oxide with water?
Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
What is the solubility of zinc in 100 grams water?
The solubility of zinc in water is very low at room temperature. Approximately 2.1 grams of zinc can dissolve in 100 grams of water at 20°C.
Why akali metals is active base than alkaline metals from their solubility's in water?
the solubility of alkali metal bases is more than the solubility of alkaline metal bases. thus the reaction: base=metal ion + OH- occus faster. since the more the OH ions the stronger the base, alkali metal bases are stronger than alkaline metal bases

What is copper's solubility in water?
Copper's solubility in water is very low, with a maximum solubility of about 0.02 grams per liter of water at room temperature. However, this solubility can increase under certain conditions such as low pH levels or presence of certain complexing agents.

Why solubility of pentamethylcyclopentadiene is high?
Methyl is electron donating group hence increasing electron density on cp and consequently on Metal, this phenomenon make the metal less electrophilic. Hence decreasing its polarity and increasing its solubility in nonpolar solvents Organic Solvents). AZK QAU ISB PAK
What is solubility order of sulphate of alkaline earth metal?
The solubility order of alkaline earth metal sulfates generally decreases as you move down the group in the periodic table. Thus, the solubility trend is: magnesium sulfate (MgSO₄) and calcium sulfate (CaSO₄) are relatively soluble, while strontium sulfate (SrSO₄) is moderately soluble, and barium sulfate (BaSO₄) is largely insoluble. Therefore, the overall order of solubility from most to least soluble is MgSO₄ > CaSO₄ > SrSO₄ > BaSO₄.
Is iron fluoride soluble?
Iron fluoride is sparingly soluble in water. Its solubility depends on temperature and the pH of the solution. In general, iron fluoride has low solubility in water compared to other metal fluorides.

What factors could affect the solubility of copper sulphate?
The factors that could affect the solubility of copper sulfate include temperature (higher temperature increases solubility), pressure (not a significant factor for solid-liquid solubility), and the presence of other solutes that may compete for binding sites with copper sulfate ions, such as other metal ions. Additionally, pH can also affect the solubility of copper sulfate as it can influence the formation of complexes with other ions.
Ph may affect the solubility of ionic compounds?
Yes, pH can affect the solubility of ionic compounds by influencing the charge on the ions. For example, changing the pH can alter the solubility of metal hydroxides by affecting the balance between the ions and their solid form. This can result in precipitation or dissolution of the ionic compound.
Why alkaline earth metal carbonates trend of solubility decreases from top to bottom?
The solubility of alkaline earth metal carbonates decreases from top to bottom due to the increasing size and decreasing charge density of the metal cations. As you move down the group, the larger cations (like Ba²⁺) have a weaker attraction to the carbonate anion (CO₃²⁻), making it less energetically favorable for them to dissolve in water. Additionally, the lattice energy of the carbonates increases at a slower rate than the hydration energy, leading to lower solubility for the heavier alkaline earth metals.
