How to calculate number of ions in a solution
WebSince we have the pOH, we could use the pOH equation to find the concentration of hydroxide ions in solution. So we would just need to plug in the pOH into this equation which gives us 4.75, which is the pOH, is equal to the negative log of the concentration of hydroxide ions. Next, we can move the negative sign over to the left side. Web29 mrt. 2016 · NaCl(aq] → Na+ (aq] + Cl− (aq] So, if every mole of sodium chloride produces One mole of sodium cations, it follows that the number of moles of sodium cation present in your solution will be equal to the number of moles of sodium chloride you dissolved to create this solution. More specifically, you know that you have
