I think what you are looking for is a material that shows amphoteric properties i.e it can act as an acid or a base in reactions. An example of this is Zinc Oxide.
It can *form* a weak acid - it is solid carbon dioxide, which in solution is carbonic acid.
Talk is an insoluble solid.
A solid acid is used for standardizing a base because it allows for accurate quantification of the base's concentration. The solid acid provides a known and stable amount of proton acceptors, enabling precise titration with the base. This method ensures reliable results and helps in determining the exact concentration of the base solution.
moles of acid = moles base = moles base/liter x liters of base used
HNO2 is a weak acid. It can donate a proton in a chemical reaction.
Cul2 is neither an acid nor a base. It is a chemical compound called copper(I) iodide, which is a solid with low solubility in water.
To obtain the solid salt resulting from an acid-base reaction in an aqueous solution, you can typically do so by evaporating the water from the solution. This will leave behind the solid salt that formed during the reaction between the acid and base. Once the water has evaporated, you can collect the solid salt for further use or analysis.
The H+ from the acid (as H3O+) and OH- from the base combine to form H2O, Thats all there is to it, it gives pure water. this is the way to neutralize acid.
When an acid and a base mix, they can form a chunky substance known as a precipitate. This occurs when the combination of the two solutions causes a chemical reaction that produces an insoluble solid. This solid material appears as clumps or chunks in the mixture.
An incense stick is neither an acid nor a base. It is a solid material that primarily consists of aromatic compounds, binders, and incense-making materials like resins and essential oils.
Acid + base conjugate base + conjugate acid
You might be referring to the Fischer-Speier reaction for producing ethyl ethanoate from the other two substances. The other product is water. By contriving to eliminate the water it is possible to favour the equilibrium of this reaction toward more of the desired substance. Please see the link for methods.
