Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g) This equation represents the reaction between solid zinc (Zn) and aqueous hydrochloric acid (2HCl) to produce aqueous zinc chloride (ZnCl2) and hydrogen gas (H2).
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.
The reaction between sodium carbonate and calcium chloride will produce sodium chloride and calcium carbonate. The balanced chemical equation for this reaction is: Na2CO3(aq) + CaCl2(aq) → 2NaCl(aq) + CaCO3(s).
Aqueous hypochlorous acid and aqueous calcium hydroxide react to produce aqueous calcium hypochlorite and water. This is a double displacement reaction where the hydrogen ion from the acid is replaced by the calcium ion, forming a new salt.
It depends on the solution in which the reaction producing it occurs. A precipitate is formed when a product of a reaction in an aqueous solution is not soluble. Instead of being dissolved in the solution, it 'precipitates' into a solid, which often is suspended in the solution and may cause a color change. Ba(OH)2 is soluble in water, and therefore will not produce a precipitate in water unless the water is over-saturated or at low temperatures.

The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl
BaCl2 + H2SO4 → BaSO4 + 2HCl Reactants Products
This reaction is:NaCl + H2SO4 = NaHSO4 + HCl
Adding a solution of Sodium Sulphate to aqueous Barium Nitrate will produce a white precipitate of Barium Sulphate with Sodium Nitrate remaining in solution.
Zn(s) + 2HCl(aq) -> ZnCl2(aq) + H2(g) This equation represents the reaction between solid zinc (Zn) and aqueous hydrochloric acid (2HCl) to produce aqueous zinc chloride (ZnCl2) and hydrogen gas (H2).
A precipitate may form in a double-displacement reaction when two aqueous solutions react to produce an insoluble solid compound.

In a combustion test, chlorocyclopropane is expected to burn to produce carbon dioxide, water, and hydrogen chloride gas. In a test with alcoholic silver nitrate, a white precipitate of silver chloride is likely to form. With aqueous sodium hydroxide, a white precipitate of silver oxide will likely form, and in a reaction with magnesium metal, hydrogen gas will be evolved with the formation of a white precipitate of magnesium chloride.
All acids produce hydrogen ions (H+) in aqueous solution.
Yes, sodium (Na) can be extracted from the electrolysis of its aqueous solution of sodium chloride (NaCl). During electrolysis, sodium ions are reduced at the cathode to form elemental sodium. Meanwhile, chloride ions are oxidized at the anode to produce chlorine gas.
A white precipitate, lead (II) chloride, and aqueous sodium nitrate would form. The chemical equation is Pb(NO3)2(aq) + 2NaCl(aq) --> 2NaNO3(aq) + PbCl2(s). This type of reaction is called a double replacement or double displacement.
