Electrolytes and pH Concepts

Electrolytes are substances that conduct electric current in aqueous solutions.
HCl is identified as an electrolyte among the options.
An Arrhenius acid releases H+ ions when dissolved in water, resulting in a solution with only H+ ions.
A change in pH from 4 to 3 signifies a tenfold increase in the concentration of hydronium ions (H3O+).

pH and pOH

A hundredfold increase in H3O+ concentration corresponds to a pH change from 3 to 1.
The pH of a 0.001 M KOH solution is determined to be 11, indicating it is basic.
A hydronium ion concentration of 1 x 10^-9 M suggests the solution is acidic, with a corresponding pH of 9.
pH is a measure of H+ concentration, while pOH measures OH- concentration in a solution.

Acid-Base Behavior

The ammonium ion (NH4+) can act as an acid.
Substances that can function as either acids or bases are referred to as amphoteric substances, with water being a prime example as it can donate or accept protons.

Chemical Reactions

Hydrolysis involves the reaction of a salt with water to produce an acid and a base.
Neutralization occurs when an acid and a base react to form a salt and water.
The dissolution of additional NaCl in a NaCl solution does not alter the pH, indicating that it remains neutral.

Types of Salts

Strong acid with strong base (SA + SB) results in a neutral salt.
Strong acid with weak base (SA + WB) forms an acid salt.
Weak acid with strong base (WA + SB) produces a basic salt.
