Which solution would cause blue litmus paper to turn red?
True [87]
An acidic solution would turn a blue litmus paper red due to the mobile and free hydrogen (H+) ions. These hydrogen ions affect the colour property of the litmus papers and thus the colour change. A litmus paper dropped into a solution of hydrogen ions turns red to indicate that the solution is acidic.

In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions)
gregori [183]

Answer:

The correct answer will be " RbF > RbCl > RbBr > Rbl".

Explanation:

The size of the given ions will be:

<u>RbCl:</u>

⇒  689kJ/mol

<u>RbBr:</u>

⇒  660kJ/mol

<u>Rbl:</u>

⇒  630kJ/mol

<u>RbF:</u>

⇒  785kJ/mol

Now according to the size, the arrangement will be:

⇒  (785kJ/mol) > (689kJ/mol) > (660kJ/mol) >(630kJ/mol)

⇒  RbF > RbCl > RbBr > Rbl

The bond among all opposite charging ions seems to be strongest whenever the ions were indeed small.
