Which of the following is weak electrolyte in solution

-H2S
-H2SO4
-HI
- HNO3
- HCI

Certain acids are considered to be strong, which means they are dissociated 100% in solution. HCl hydrochloric acid

HNO3 nitric acid
H2SO4 sulfuric acid
HBr hydrobromic acid
HI hydroiodic acid
HClO4 perchloric acid

You ought to memorize this list, because almost every other acid is weak. The most common example used by teachers is HCl. Watch out for a teacher who tries to trip you up by using another strong acid on the test while having used HCl all the time in class.

The weak electrolyte in solution among the options given is H2S (hydrogen sulfide).

To determine which of the following is a weak electrolyte in a solution, we need to understand the concept of electrolytes. An electrolyte is a substance that, when dissolved in water or melted, produces ions that can conduct electricity.

To identify a weak electrolyte, we look for substances that partially ionize or dissociate into ions when dissolved in water. Weak electrolytes only produce a small number of ions compared to strong electrolytes, which fully ionize.

Now, let's examine the given options:

- H2S (Hydrogen sulfide): H2S is a weak acid and a weak electrolyte in solution because it partially ionizes, producing hydrogen ions (H+) and sulfide ions (S2-).
- H2SO4 (Sulfuric acid): H2SO4 is a strong acid and a strong electrolyte in solution because it fully ionizes, producing two hydrogen ions (H+) and one sulfate ion (SO4^2-).
- HI (Hydroiodic acid): HI is a strong acid and a strong electrolyte in solution because it completely ionizes, forming hydrogen ions (H+) and iodide ions (I-).
- HNO3 (Nitric acid): HNO3 is a strong acid and a strong electrolyte in solution because it fully ionizes, generating hydrogen ions (H+) and nitrate ions (NO3-).
- HCl (Hydrochloric acid): HCl is a strong acid and a strong electrolyte in solution because it fully ionizes, producing hydrogen ions (H+) and chloride ions (Cl-).

Therefore, among the given options, H2S is the weak electrolyte in solution.
