dio nucleic acid a.k.a. DNA
Limestone contains calcium carbonate, which reacts with acid (such as hydrochloric acid) to form carbon dioxide gas. The release of carbon dioxide gas creates bubbles or fizzing on the limestone surface.
If the acid is hydrochloric acid, the solution bubbles, and the zinc diminishes and may disappear if there's enough acid. If hydrochloric acid was used, the reaction would be Zn + HCl --> ZnCl2 + H2 . The bubbles are hydrogen gas. The zinc chloride would be dissolved in aqueous solution.
is soluble in water and will fizz when hydrochloric acid is added
Carbon dioxide gas bubbles out when drops of hydrochloric acid are dropped on marble. This reaction occurs because the hydrochloric acid reacts with the calcium carbonate in the marble, producing carbon dioxide gas as a byproduct.
When excess hydrochloric acid has been added to an evaporating dish with magnesium, you will observe bubbling and fizzing as the magnesium reacts with the acid. Once all the magnesium has been consumed in the reaction, no more bubbles will be produced, indicating that excess acid is present.
A chemical reaction would occur where sodium reacts with hydrochloric acid to produce hydrogen gas and sodium chloride (table salt). The reaction will generate heat and may release hydrogen gas, which is flammable.
When aluminum shavings are added to hydrochloric acid, a chemical reaction occurs which produces hydrogen gas and aluminum chloride. The hydrogen gas is released as bubbles, while the aluminum chloride remains dissolved in the acid solution. This reaction is exothermic and can generate heat.
First off. You should NOT be drinking hydrochloric acid. Second, hydrochloric acid added to another acid is just that, more acid.
When hydrochloric acid is added to zinc powder, a chemical reaction occurs where zinc reacts with hydrochloric acid to produce hydrogen gas and zinc chloride. The hydrogen gas is evolved as bubbles, and the zinc chloride remains in solution. This is a typical example of a single displacement reaction.
is Ca(OH)2 is soluble in water and will hissing when hydrochloric acid is added
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
When iron powder is added to hydrochloric acid, a chemical reaction takes place which produces hydrogen gas and iron(II) chloride. The iron powder dissolves in the acid and the hydrogen gas is released as bubbles. The iron chloride formed remains in solution.
