Answer:
Solutions are always homogeneous.
Explanation:
Solution:
Solution are considered homogeneous because in solution the ratio of solute and solvent remain the same throughout the solution. Both solute and solvent are chemically combined and form a new substance.
In solution the particles of solute can not be seen through naked eye.
When the light is passed through the solution it can not scattered.
Example:
When salt is dissolve in water it makes a solution.
The solution also exist in gaseous form. For example oxygen and many other gases dissolved in nitrogen also form a solution.
Mixture:
In mixture substance are physically combined. In mixture every every individual particle retain their properties.
It can be consist of solid, liquid and gas.
Examples:
Sand in water is also a mixture.
Oil in water form mixture.
the physical properties of ammonium sulphate are colorless gas, less dense than air, pungent shell, very soluble in water, alkaline gas
Answer:
Hydochloric acid
HCl
Explanation:
The name of the compound that gives hydrogen ion and chloride ions in the solution state is Hydrochloric acid.
Hydrochloric acid is made up of one atom of hydrogen and 1 atom of chlorine. We can also say, it is made up of 1 mole of hydrogen and 1 mole of chlorine.
The formula of this compound is HCl;
In solution:
HCl
→ H⁺ + Cl⁻
There are different types of indicators for different neutralization reactions. The best indicator for giving a colour change at the equivalence point of a neutralization reaction depending on the pH range of a particular indicator and the equivalence point of the reaction. For instance, the best indicator for a neutralization reaction that involve the titration of NaOH with an acid which result in 9.00 equivalence point is phenolphtalein. This is because the equivalence point which is 9.00 is within the pH range of the indicator, which is between 8.0 to 10.1.
