Answer:
Your question is not specific enough so, I've given you a list of things that occurs, when a reaction has taken place.
It could be in the form of:
Heat or light given off or a colour change.
Hope this helps!
Answer:The endpoint does not correspond exactly to the equivalence point
At the endpoint, a change in a physical quantity associated with the equivalence point occurs.
At the equivalence point, the mole number of equivalents of reagent added is equal to the mole number of equivalents of analyte present.
Explanation:
The end point is always indicated by some physical property that changes such as colour. At the equivalence point, the mole number of equivalents of reagent added is equal to the mole number of equivalents of analyte present. The equivalence point cannot be physically observed but can be deduced after a titration curve is plotted.
Answer:
When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate. Only the solute will remain in the evaporating dish.
hope it helps! please mark me brainliest
thank you! have a good day ahead
if u follow me, I will follow u back
The net ionic equation of hydrobromic acid would be HBr = H+ + Br-. As we can see, the HBr compound dissociates into ions where one ion is the hydronium ion which characterizes an acid. According to Arrhenius, an acid is a compound which releases hydronium ion in solution.
