Question

Which of the following are strong electrolytes? Hcl hc2h3o2 nh3 kcl

Answer 1

Answer;

HCl and KCl

Explanation;

• Strong electrolytes are strong bases and acids.
• HCl is a strong acid; it dissociates completely to form H+ and Cl- ions. Thus, it is a strong, rather than weak, electrolyte.
• CH3COOH is acetic acid, a weak acid. Only some of it will dissociate (to H+ and acetate ions), thus, it will only be a weak electrolyte.
• NH3 will react with water as a weak base: NH3 + H2O → NH4+ + OH-. It will thus also be a weak electrolyte.  
• KCl is a soluble ionic compound, and as such, it will be a strong electrolyte.

Answer 2

Which includes strong electrolytes are HCl and KCl.

Further Explanation

The electrolyte solution is a solution that can conduct an electric current. In an electrolyte solution, the molecules break down (dissociate) into positive and negative electrically charged particles called ions (positive ions). The positive ion produced is called a cation and the negative ion produced is called an anion. The sum of the charges of positive ions and negative ions will be the same so that the charge of the ions in the neutral solution. These ions then conduct electricity.

The electrical conductivity of electrolyte solutions depends on the type and concentration. Some electrolyte solutions can conduct electrical current well even though the concentration is small, this solution is called a strong electrolyte. While electrolyte solutions that have weak conductivity even though the concentration is high are called weak electrolytes.

Strong electrolyte solution, which is a solution where all the molecules break down into ions (fully ionized). Because of the large number of electrically conducting ions formed, the conductivity is also strong. Generally, a strong electrolyte solution is a salt solution.

Characteristics of Strong Electrolyte Solutions

• Conducting electric current is strong or good
• Perfectly ionized
• The degree or degree of ionization (a) a = 1
• If tested, strong electrolyte solutions have bright lights and many gas bubbles appear.

Example :

Salt (NaCl, KCl, CuSO4, and KNO3),

Strong acids (HCl, HI, HBr, H2SO4, and HNO3), and

Strong bases (NaOH, Ca (OH) 2, Mg (OH) 2 and KOH)
