Cesium Sulfite is formed from the Cs cation and the SO₃⁻² anion. The correct formula for this compound is Cs₂SO₃.
<h3>What is Cation ? </h3>
Cations are positively charged ions. It forms when an element lose one or more electrons.
<h3>
What is Anion ? </h3>
Anions are negatively charged ions. It form when an element gains one or more electrons.
Symbol Cs⁺¹ SO₃⁻²
Valency +1 -2
Formula of the compound is Cs₂SO₃.
Thus from the above conclusion we can say that Cesium Sulfite is formed from the Cs cation and the SO₃⁻² anion. The correct formula for this compound is Cs₂SO₃.

Vapor pressure is defined as <span> the </span>pressure<span> exerted by a </span>vapor<span> which is in equilibrium with liquid, at a given temperature, in a closed system. If vapor pressure is high, it suggest that escaping tendency of liquid is high. This will result in higher pressure level in manometer.
In present case liquid A (i.e option F) has highest level in manometer, suggesting that it has highest vapor pressure.
