Question

Which of the following statements is (are) true? Correct the false statements.

1. A concentrated solution in water will always contain a strong or weak electrolyte.
2. A strong electrolyte will break up into ions when dissolved in water.
3. An acid is a strong electrolyte.
4. All ionic compounds are strong electrolytes in water.

Short answer

In the above statements,

a and c are false

b and d are true

Step-by-step solution

Definition of strong electrolyte

A solution/solute that completely, or almost completely, ionizes or dissociates in a solution is defined as strong electrolytes

Find whether the statement is true or false

A. A concentrated solution is one in which there is a large amount of substance present in a mixture. A concentrated solution may contain strong, weak or a non electrolyte dissolved in water

So the statement is false

B. Strong electrolyte easily dissociate completely into its component ion. Hence, they are soluble ionic compounds

So the statement is true

C.Strong electrolytes can be either strong acids or strong bases. Not all acids are strong electrolytes because not all acids are strong. Some acids are weak acids

So the statement is false

D.Ionic compound consists of a metal ion and a non metallic ion. Upon reaction with water, ionic compounds will be released as positive and negative ions

So the statement is true
