What are some non examples of precipitate?
Silver Chloride (AgCl)Silver Bromide (AgBr)Silver Iodide (AgI)Barium Sulfate (BaSO4)Calcium Carbonate (CaCO3)to list a few...Some Others:BaCrO4 (not molecular - ion lattice)PbSO4Hg2SO4BaSO4CaSO4Ca3(PO4)2Fe(OH)3Pb(OH)2Al(OH)3Co(OH)2Cu(OH)2CuSNiSCo2O3Hg2Br2Hg2Cl2Hg2I2AgCrO4Ag3PO4FePO4Fe2S3Fe2(CO3)3PbCl2PbBr2PbI2PbSSome Notes on Solubility in H2O: (if a compound IS soluble it will NOT precipitate)1. EXCLUDING NaOH and KOH (which are very soluble), many -OH salts are only slightly soluble [i.e. some may precipitate out of solution with lowered temperatures or high concentrations, ex: Ba(OH)2, Sr(OH)2, Ca(OH)2]2. Similarly, many salts containing the following ions are also only slightly soluble (and may precipitate out of solution depending on the experimental conditions): S2-, CrO42- (above examples of precipitates), CO32-, PO33-3. Alkali metal salts are usually soluble (i.e. salts with Li+, Na+, K+ etc.)4. Most halide salts are soluble (Cl-, Br-, I-) EXCEPT when combined with Ag+, Pb2+, Hg22+ (see examples above) and a few other metals (esp. towards the right of the transition metals and into the "poor" metals on the periodic table) à in general, silver, lead and mercury often lead to compounds that will precipitate out of water (Fe3+ can also lead to many precipitates)Notable exception: Pb(NO3)2 IS soluble and WILL NOT precipitate out5. Most sulfate (SO42-) salts ARE soluble (with some common exceptions listed above)6. NO3- and NH4 salts are usually soluble7. There are several phosphate salts that are insoluble (see above for examples)
What are the names of the following compounds CaCl2 CuCl AgCl Mg3P2?

Which of the following elements would be more reactive with other elements boron?
Boron is more reactive with other elements compared to carbon. Boron is a metalloid that tends to form covalent compounds in compounds such as borides. Its reactivity is influenced by its electron configuration and small atomic size.
Why does potassium permanganate and sodium bisulfite form a brown precipitate?
The brown precipitate is MnO2, it is the product of the following redox in neutral environment:For each half reaction:MnO4- + 4H++ 3e- → MnO2 + 2H2O REDUCTIONHSO3- + H2O → SO42- + 3H+ + 2e- OXIDATIONOverall: Permanaganate half reaction x2 + Bisulfite half reactionx32MnO4- + 3HSO3- + 8H+ + 3H2O + 6e- → 2MnO2 + 3SO42- + 4H2O + 9H+ + 6e-Cancelling like terms:2MnO4- + 3HSO3- → 2MnO2 + 3SO42- + H3O+Note that all species are balanced, all charges are balanced and the brown precipitate MnO2 is accounted for. The reaction also predicts that acid is formed in the process.
How do you classify compounds as soluble or insoluble following the rules for sloubility?
Compounds are classified as soluble if they dissolve in a solvent to form a homogeneous mixture. Compounds are classified as insoluble if they do not dissolve in the solvent and form a precipitate instead. Solubility rules are used to predict if a compound will be soluble or insoluble based on the type of ions present and their interactions with the solvent.
How many of the following compounds are insoluble in water KC2H3O2 CaSO4 SrS AlPO4?
CaSO4 and SrS are insoluble in water, while KC2H3O2 and AlPO4 are soluble in water.
What is the function in the following reagents used in the extraction and precipitation of DNA?
The function of phenol-chloroform is to denature proteins and extract DNA into the organic phase, while the function of isopropanol is to precipitate DNA by causing it to become insoluble in the solution.
Will precipitation occur when the following solutions NaNO3 and NiSO4 are mixed?
No, precipitation will not occur when NaNO3 and NiSO4 are mixed because neither compound forms an insoluble precipitate with the other. Both NaNO3 and NiSO4 are soluble in water.
To determine which of the products and precipitation reaction is the precipitate which of the following should you follow?
To determine the precipitate in a precipitation reaction, you should follow solubility rules. These rules provide guidance on the solubility of various compounds in water, helping you identify which compound will form a solid precipitate. By comparing the ions present in the reactants and applying solubility rules, you can determine the precipitate formed in the reaction.

Will precipitation occur when the following solutions Na2CO3 and AgNO3 are mixed?
Yes, a precipitation reaction will occur. Mixing aqueous solutions of Na2CO3 and AgNO3 will produce solid silver carbonate (Ag2CO3) as one of the products, which is insoluble in water and will precipitate out of the solution.
Which of the following best describes a double replacement reaction?
Atoms in one compound switch places with atoms in another compound.
Which of the following compounds can have stereoisomers?
Compounds with chiral centers can have stereoisomers.
What are signs for a chemical reaction of NaCl?
For example formation of a precipitate as in the following reaction: NaCl + AgNO3 = AgCl(s) + NaNO3 Silver chloride is a white precipitate.
Mixing silver nitrate with table salt?
When you mix silver nitrate with table salt (sodium chloride), a white precipitate of silver chloride forms. This reaction occurs because silver nitrate and table salt react to form insoluble silver chloride. This reaction is often used in chemistry experiments to demonstrate the formation of a precipitate.
Is the following combinations expected to be soluble or insoluble polar solute and non-polar solvent?
A polar solute is expected to be soluble in a non-polar solvent. This is because "like dissolves like" – polar molecules tend to dissolve in polar solvents, and non-polar molecules dissolve in non-polar solvents.
