Answer :
Strong acid does not conduct electricity. Question 4} A. H30 Question 5 } B. NaOH + CH3COOH
Answer:
For 3: The correct answer is Option A.
For 4: The correct answer is Option C.
For 5: The correct answer is Option D.
Explanation:
- For 3:
There are 2 types of solutions on the basis of pH.
An acid is defined as the chemical substance which looses hydrogen ions in a solution.
A weak acid does not completely dissociates into its ions but a strong acid completely dissociates into its ions when dissolved in water.
A base is defined as the chemical substance which looses hydroxide ions in a solution.
A weak base does not completely dissociates into its ions but a strong base completely dissociates into its ions when dissolved in water.
Hence, the correct answer is Option A.
- For 4:
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
For the given chemical equation:
[tex]H_2O+HCl\rightarrow H_3O^++Cl^-[/tex]
[tex]H_2O[/tex] is considered as a bronsted-lowry base because it is accepting hydrogen ion to form hydronium ion
HCl is considered as a bronsted-lowry acid because it is donating hydrogen ion to form chloride ion.
Hence, the correct answer is Option C.
- For 5:
Neutralization reaction is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule.
[tex]HX+BOH\rightarrow BX+H_2O[/tex]
For the given options:
Option A:
The chemical equation follows:
[tex]NH_3+HCl\rightarrow NH_4Cl[/tex]
This is an example of neutralization reaction because ammonia is considered as a base and when it reacts with HCl, it leads to the production of salt.
Option B:
The chemical equation follows:
[tex]NaOH+CH_3COOH\rightarrow CH_3COONa+H_2O[/tex]
This is an example of neutralization reaction.
Option C:
The chemical equation follows:
[tex]2HNO_3+Ca(OH)_2\rightarrow Ca(NO_3)_2+2H_2O[/tex]
This is an example of neutralization reaction.
Option D:
The chemical equation follows:
[tex]H_2SO_4+2NaCl\rightarrow 2HCl+Na_2SO_4[/tex]
This is an example of double displacement reaction.
Hence, the correct answer is Option D.
