Calculating Ion Concentrations in Solution

We know that concentration is typically expressed with molarity, which is moles per liter. But how do we know how many moles of solute are present in solution when an ionic solid dissolves in water? It's not so simple because these will dissociate into individual ions, so there is some extra stoichiometry to do!

I love how you have such a good plan and format for It lets you just crank them out, your channel is one of the best channels focusing on education

[leonelisaiah]

ive been struggling with concentration for so long, thank you so much for making such a good explaination!!

[nelsoncampos]

Good explanation....all due to a good vocalization speed...which in turn allows to assimilate the information...plus you kept it simple as it should be

[dineshdharmadhikari]

Expert presentation as always
👌 Very good my favourite teacher

[airy-ice]

Thank you so much! Simple and straightforward

As a student I remember always having problems with the notion that the molar mass of the compound on one side of the equation resulted in two ions potentially have the same molar mass...never made sense to me from an algebraic point of view, especially since everything was always a percentage and balanced. Always seemed to me that Na had to have 22.99/58.44 of the molar mass and Chlorine had to have 35.45/58.44 of the molar mass. Then suddenly two ions could have twice the molar mass...never added up. Only when you broke it back up into their mass did you realize there was 10 grams of NaCl on one side of the equation disassociated into 6 grams of chlorine and 4 grams of sodium. It might be smart to show mass breakdown as it correlates to molar mass results to show that they are indeed balanced.

This has helped me tremendously, thank you so much for all of your wonderful videos! You're a great teacher

Professor dave here is a question in physics as i didnt understand your other video



A system consists of electrons and protons only.It contains 150 electrons and has a total charge of +22e.What is the mass of the system

[zaz]

He read my chemistry exercise and came here
Perfect explanation

[davorpantelic]

1:44 . How individual atoms(ions) of the compound have the same M as the whole compound NaCl. For example 10g of NaCl converted to M is 0.171 M how then both Na and Cl ions have same 0.171M in that compound, Should it be 0.0855M for each atom(ion) . Can someone explain ?

[muminochanel]

Thank you so much this lesson has helped me a lot!

[TheJuicylucy]

Wow this video would of been great LAST WEEK 😂😂😂😂😩😩😩

[Mangomanjiro]

Thank you so much for the explanation:))

[allenshaalen]

Sir can you teach how to count fertilizer such as calcium nitrate, potassium nitrate, phosphoric for example calcium nitrate 16kg, potassium nitrate 11kg, mkp2.5kg, mgs5kg mixed well in separate tank how to calculate cation and anion. Pls tq

[judithn]

Great video! Keep up the good work! Definitely subscribed

[mittalpatel]

Hi. Could u pls tell me how can i get mg ionic concentration in Mgcl^2.6h20 1534 gm in 3.5 liter???

[ericgodwin]

How do you solve with only being given the moles of the solution and not the liters

[pro.glowup]

thank you so much for this awesome explanation .
so how do i go about when dealing with complex compounds ? for example im given 0.56M of NaSO4.6H2O and i have to find the concentration of Nickel

[evi]

What if it’s two ions ? Is it still the the number per mol
