If you mean why are they soluble in water, it is because the hydrogen in water has a slight positive charge and the oxygen in water has a slight negative charge, making an ionic compound (such as one containing sulphate) which has charges itself, readily soluble to adjoin these charges.
What else can I help you with?
What are some examples of soluble things?
powdered milk, alum, salt, sugar, copper sulphate
Are covalent soluble?
Covalent compounds can be soluble, depending on their polarity and structure. Covalent compounds that form hydrogen bonds or have polar groups are more likely to be soluble in polar solvents, while nonpolar covalent compounds are more likely to be soluble in nonpolar solvents.
Are inorganic compounds soluble?
Some are and some are not. Some water soluble inorganic compounds include ammonia (NH3), sodium chloride (NaCl), and copper sulfate (CuSO4). Some water insoluble inorganic compounds include silicon dioxide (SiO2), calcium carbonate (CaCO3), and lead iodide (PbI2)
How can dissolving be used to separate components of a mixtures?
Some compounds are soluble, other are not soluble; by filtration they are separated.
Do chemical compounds remain in the organism permanently?
Some do and some do not. Water-soluble compounds can pass out of an organism fairl easily. Some compounds, such as DDT, however, do not leave the body.
Is aromatic compound water soluble or not?
Aromatic compounds are generally insoluble in water due to their nonpolar nature. This is because water is a polar solvent and does not interact favorably with nonpolar molecules. However, some aromatic compounds can have functional groups that make them partially soluble in water, but overall, their solubility tends to be low.
What substance is not soluble in water?
actually in chemical bonding we discuss two type of compounds one is polar and one is non polar compounds. in both of these two only polar compounds are soluble in water and non polar compounds are not soluble in water and they are soluble in polar solvents like benzene and CCl4.
Are all ionic compounds Almost all ionic compounds are soluble in water?
Almost all. Some such as calcium carbonate, silver chloride are not soluble. Generally ionic compounds are soluble in water due to their ionic bonds which makes them easy to dissociate in polar solutions such as water.
Is zinc soluable?
No. Zinc is not soluble. It is a metal like gold is not soluble in water. There are some compounds of zinc like ZnCl that are soluble. I just learned this last unit in Chem class.
Are ionic bonds soluble in water?
Ionic bonds are not soluble in water because they are not individual entities that can dissolve. However, ionic compounds, which are formed by ionic bonds, can often dissolve in water because the individual ions can separate and disperse in the water through the process of ionization.
What cations always form soluble compounds?
Cations don't always form soluble compounds. In general, ionic compounds are soluble in very polar solvents such as water and insoluble in nonpolar solvents because the charged ions can be solvated only by polar solvents. Some ionic compounds are insoluble even in water, however.
What is the chemical reaction with whisky and a barrel?
Alcohol extract some soluble compounds from the oak barrel.
