Answer:
it is D
Explanation:
NaOH and chlorine gas
Electrolysis of Aqueous NaCl Since water can be both oxidized and reduced, it competes with the dissolved Na+ and Cl– ions. Rather than producing sodium, hydrogen is produced. ... The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas.
Answer:
a. True
Explanation:
The data curve for OCI-/H3O appears to be similar to C2H3O2-/H3O because protons have not dissociated with conjugate base. This conjugate base is strong and hold proton in solution while acids try to dissociate it.

Answer:
Expose the paper to the atmosphere or moisture
Explanation:
An interesting experiment that demonstrates the equilibrium of complexes is that of the invisible ink.
The invisible ink is pink colored [Co(H2O)6]Cl2 which is essentially colorless and pale when it is used to write on paper. This complex is almost colorless when dilute. Therefore, when it is used in writing, the writing can not be seen.
However, if the paper is left to stand or allowed to absorb moisture; the following equilibrium is set up:
[Co(H2O)6]Cl2 ⇄ [CoCl2(H2O)2] + 4H2O
The formation of blue [CoCl2(H2O)2] on standing or exposure to moisture enables the colored writing to be easily read.
