Nowhere. I assume you are talking about mixing solutions. The sodium ions and sulpahate ions remain in solution.
It produces Sodium hydroxide and Hydrogen
Assuming they are dissolved in water the mixture turns green. Presumably the copper and chloride associate and the sodium and sulphate remains clear. The cystalised substance remains green although the colour deepens when it is dry.
It will fizz up and overflow with lots of bubbles.
When dilute hydrochloric acid mixes with sodium hydroxide, a neutralization reaction occurs, producing sodium chloride (table salt) and water. The equation for this reaction is: HCl + NaOH -> NaCl + H2O.
Jacob is carrying out a neutralization reaction. Sodium hydroxide (NaOH) and hydrochloric acid (HCl) react to form sodium chloride (NaCl) and water (H2O). This is a common reaction where an acid and a base neutralize each other to produce a salt and water.
When a test solution mixes with sodium hydroxide, a chemical reaction may occur depending on the components of the test solution. Sodium hydroxide is a strong base and can react with acidic components in the test solution, resulting in neutralization and the formation of water and a salt. The reaction may also cause a change in color or precipitation, depending on the specific chemical properties of the test solution.
No, because calcium is a less reactive metal than sodium, therefore the calcium will not replace/displace the sodium from the sodium hydroxide. There will be no reaction.
Whenever an acid reacts with a metal carbonate, a salt, plus water and carbon dioxide are produced as products. As for the example give in the question, sodium sulphate is the salt, as shown in this balanced chemical equation: H2SO4 + Na2CO3 -------> Na2SO4 + H2O + CO2
It is a chemical change, as sodium cannot evaporate (or water go to water vapor) without added heat. The main gas produced in this highly exothermic chemical reaction is hydrogen, liberated from the water by the combination of a hydroxide radical (OH) with the sodium, yielding a sodium hydroxide (NaOH) solution. The heat released is typically sufficient to ignite and burn both the sodium and the released hydrogen. So pure sodium metal oddly appears to catch fire and burn when placed in water.
When HCl (hydrochloric acid) mixes with heated copper, the copper reacts with the acid to form copper(II) chloride and hydrogen gas. The reaction releases heat and the copper may also appear to be dissolved as it reacts with the acid.
