    Final Volume
AI Thread Summary
To achieve a higher concentration of calcium in a known volume of water, the equation C1V1 = C2V2 is essential. Here, C1 represents the initial concentration of calcium, V1 is the initial volume, C2 is the desired final concentration, and V2 is the total final volume after adding the second solution. To find the volume of the second solution needed, rearrange the equation to solve for V1. By substituting the known values into the equation, one can calculate the required volume of the second solution with a known concentration of calcium to reach the desired final concentration. This method allows for precise adjustments to achieve the target concentration without altering the concentration of the added solution.

Hi
I have a known volume of water with a known concentration of calcium.
I want to bring that volume up to a new (slightly) higher volume with a new (slightly) higher concentration. To do this I am adding a solution with a known concentration of Ca but cannot remember how to calculate the volume (of the second solution) I need to get to the final concentration. I cannot adjust the concentration of the second substance, I can only adjust the volume.
thanks

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
