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

HCl and KCl

Which includes strong electrolytes are HCl and KCl.

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

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)

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

a. hope i'm right
