In this reaction, the precipitate formed would be silver chromate due to the double displacement reaction between sodium chromate (Na2CrO4) and silver nitrate (AgNO3). Silver chromate is insoluble in water, so it will precipitate out of the solution as a solid, appearing as a yellow precipitate.
The chemical reaction is:Na2Cr2O7 + 2 NaOH = 2 Na2CrO4 + H2O
Water is the product of the reaction between hydrogen and oxygen.
The product of a reaction between an acid and a base is a salt and water. This reaction is called neutralization and it involves the transfer of a proton (H+) from the acid to the base to form water, while the remaining ions combine to form a salt.
The reaction between barium chromate (BaCrO4) and hydrochloric acid (HCl) produces barium chloride (BaCl2), chromium(III) chloride (CrCl3), and water (H2O). The balanced chemical equation for this reaction is: BaCrO4 (s) + 2HCl (aq) -> BaCl2 (aq) + CrCl3 (aq) + H2O
Magnesium chromate remains insoluble in water.
This is a neutralization reaction. This reaction should result in producing a salt and water. Sodium chromate is the salt in this instance.
The by-product is water.
When potassium chromate dissolves in water, it produces potassium ions (K⁺) and chromate ions (CrO₄²⁻).
The reaction between a base and an acid tends to produce a salt and usually water (H2O). Salts are ionic compounds that form through a reaction called a neutralization reaction between bases and acids.
It is a Synthesis reaction (also called Combination reaction) and is Exothermic , producing Sulfuric acid.
Lead chromate has a low solubility in water due to the strong electrostatic forces between the lead and chromate ions, which hold the compound together in a solid form. These forces prevent the ions from separating and dissolving in water, resulting in poor solubility.
