Barium nitrate mixed with potassium phosphate?
The solubility of barium is somewhat mixed---it can be soluble with notoriously insoluble things like hydroxide, and it can be insoluble with other somewhat insoluble anions like sulfate. However, chromate is one anion that is almost always insoluble unless it is paired with an alkali metal. So mixing these two compounds will give you a BaCrO4 precipitate.
Describe what happens to a saturated solution of sugar in water when the temperature of the solution is suddenly lowered by 10oC.?
this is a product of science. and not always will it become one of the most scientific methods but this is will work.... i don't know what i am talking about. thank you anways. sorry that i couldn't help you. THE PERSON THAT WROTE THIS IS WRONG!
A solution is always a liquid. comment.?
A solution is not always a liquid: An alloy like brass is a solid in solid solution, and air is a gas in gas solution.
With what solution does sodium nitrate not form a precipitate?
Sodium nitrate (NaNO3) never forms a precipitate when considered with standard rules of solubility. If it was mixed with another solution of the form XA, where X is a cation and N is an anion, no matter what the results were, both results would be soluble. NaNO3 + XN ---> XNO3 + NaN By solubility rules, any ionic compound containing a nitrate is always soluble, so the product XNO3 would be soluble no matter what the cation "X" was. Also by solubility rules, any ionic compound containing a cation from Group I is always soluble. Regardless of what the anion "N" is, the product NaA would always be soluble since sodium (Na) is located in Group I of the periodic table of elements.
Can a mixture of salt and water be a solution?
A mixture of salt and water is always a solution.
What is aqueous silver nitrate and potassium bromide combine to form a precipitate?
When a substance is aqueous, it means that it is dissolved in water. In aqueous reactions, the reaction is always a double replacement reaction, meaning one ion of a compound will switch with an ion from the other compound. A precipitate is an substance that is not soluble in water, meaning it cannot be dissolved. You can tell whether or not a substance is precipitate using a solubility chart. Therefore, using a solubility chart, we can tell that the product silver bromide will be the precipitate and the product potassium nitrate will be aqueous.
What is the product of Potassium Carbonate and Iron III Nitrate?
Fe2(CO3)3(s). Carbonate compounds are notoriously insoluble, whereas K+ and NO3- are almost always soluble with everything. That is why a carbonate precipitate forms.
What is potassium always found as?
In nature, potassium is always found as one or more of its compounds.
Why are precipitation reactions also called double displacement reactions?
They aren't. Double displacement (metathesis) sometimes forms a precipitate, but not always, and it would be silly to call it a "precipitation reaction" if no precipitate was formed. Formation of a precipitate is, however, one way to tell that a reaction has occurred. If everything just stays in solution, then it's meaningless to call it a "reaction" since there has been no change. The evolution of a gas is another method for determining that a reaction has occurred, as is a change in color (this often indicates a change in oxidation state as well, though not always).

Is it true that nitrates are almost always soluble and do not form a precipitate?
Yes, it is true.
Is a mixture always a solution?
yes, a solution is always a mixture

Are clouds always white?
No, clouds are not always white. Their color depends on if they are a precipitate, the time of day, and the color of the sky in general.

What are all the oxidation numbers of Potassium?
