Question:

Which of the following has maximum value of cation/anion ratio?

Updated On: Jul 7, 2022

KCl
NaCl
$\ce{CaF_2}$
$\ce{MgCl_2}$

The Correct Option is C

Solution and Explanation

Among the three options $ {KCl, NaCl}$ and $ {MgCl_2}$ , the size of anion is same. So larger the cation, larger will be the cation/anion ratio i.e., KCl will have larger cation/anion ratio among the three. So, we left with two options KCl and $ {CaF_2}$ . Among these two $ {CaF_2}$ will have maximum value of cation/anion ratio because decrease in ionic radii of anion from $ {Cl^{-}}$ to $ {F^{-}}$ does not overcome the effect of decrease in ionic radii of cation from K+ to $ {Ca^{2+}}$.

Notes on The solid state

Concepts Used:

Solid State

Solids are substances that are featured by a definite shape, volume, and high density. In the solid-state, the composed particles are arranged in several manners. Solid-state, in simple terms, means "no moving parts." Thus solid-state electronic devices are the ones inclusive of solid components that don’t change their position. Solid is a state of matter where the composed particles are arranged close to each other. The composed particles can be either atoms, molecules, or ions.

Types of Solids:

Based on the nature of the order that is present in the arrangement of their constituent particles solids can be divided into two types;

Amorphous solids behave the same as super cool liquids due to the arrangement of constituent particles in short-range order. They are isotropic and have a broad melting point (range is about greater than 5°C).
Crystalline solids have a fixed shape and the constituent particles are arranged in a long-range order.
