Potassium sulfate or K₂SO₄ is a strong electrolyte which means that it will completely dissociate into ions when dissolved in water. The dissociation reaction is as follows:
K₂SO₄ → 2K⁺ + SO₄²⁻
This means that the dissociation of 1 mol of K₂SO₄ solution will yield 2 moles of K⁺ and 1 mole of SO₄²⁻. Molarity is a measure of concentration defined as moles divided by the volume of solution. In this case, given that the volume is constant, from stoichiometry, the concentration of K⁺ ions would be twice of 0.600 M which is 1.200 M. On the other hand, the concentration of SO₄²⁻ is 0.600 M by stoichiometry.
Answer:
The numbers, positive, negative signs and the symbol of elements are used to represent the ions.
Explanation:
Steps to write the ions:
- Write the symbol of an element. For example in case of magnesium we would write Mg.
- In second step write the number of electrons in superscript that are lost or gained by an atom. For example magnesium atom loses two electrons written as followed, Mg².
- In third step write the charge as superscript after the numbers. For example, magnesium loses two electrons that's why we put the positive sign after 2, because by losing the electrons cations are formed. Mg²⁺
- If the atom of an element lose or gain only one electron then 1 is omitted and only the negative or positive sign are written on superscript. For example in case of sodium cation and chlorine anion, Na⁺ , Cl⁻.
