Solution Stoichiometry - Finding Molarity, Mass & Volume

This chemistry video tutorial explains how to solve solution stoichiometry problems. It discusses how to balance precipitation reactions and how to calculate the molarity or the concentration of a solution, the volume of reactant needed or the mass of solid product / precipitate that can be produced in the chemical reaction. This video contains plenty of examples and solution stoichiometry practice problems. In addition, it explains how to identify the limiting reactant and how to calculate the mass of product produced.

[@TheLucanicLord]

8:51 The other way to think about it is to put the stoichiometric number _under_ its own side, like (M1 V1) / S1 = (M2 V2) / S2. You can then see that if it's twice as "good", you only need half as much. Because quantity has a quality all of its own.

[@Lifejourney-j9z]

I just want to ask on the 4th question, why did you use sodium phosphate instead of calcium chloride to find the mass of calcium phosphate produced?? Because in the reaction, sodium chloride was limiting... Please explain, maybe I'm behind. I'll really appreciate it Sir. Thank you

[@_linylienne_7787]

You saved my life again 🥰

[@sofzhuk1188]

my lab is due soon and you saved me

[@yishaogu4936]

For problem #4, isn't Calcium Chloride the excess reactant and Sodium Phosphate the limiting reactant, so how did you get less product from calcium chloride then sodium phosphate?

[@sadgemain5220]

that's what im confused about too. he used the excess reactant to calculate, i think he did it wrong. the actual answer should have been 1.44 g since you would have needed to use the LR

[@xtomy_887]

@@sadgemain5220 He says at the end that the answer is the one that came from the LR

[@awkwardkoreanboy]

Quick question, does the order of the chemical equations matter? For example, in problem 2, you wrote out Pb(NO3)2+2KI -----> PbI2+2KNO3. Would the opposite (2KI+Pb(NO3)2 -----> KNO3+PbI2) be incorrect?

[@spookypenguinsoldier8595]

awkwardkoreanboy no either way works

[@Eyeh8t3leyef3]

I was going to respond but, I’m a little late for that lol. Short answer though, no. As long as you multiply both sides of the fractions correctly then divide, you’re all good 😂.

[@chi_chi6738]

Very late😂😂

[@thirisharadhakrishnan5341]

In question 2, why were the coefficients switched? Shouldn't there be 2 KI for every 1 Pb(NO3)2, so M1V1=2(M2V2), as in more of KI in comparison to PB(NO3)2 and not the other way 2(M1V1)=M2V2

[@anon102]

Yup he got that one wrong

[@starjumperrr]

we are trying to make it equal on both sides. so if there is 2 mol KI for every 1 mol Pb(NO3)2, we have to multiply the side relating to Pb(NO3)2 times 2 to make the moles equal

[@zstephen5828]

9:49 you are forgetting the significant digits here. shouldn't M be 0.13 instead of 0.1277 because all the given numbers in the question contain 2 significant digits(i.e. 37 mL, 42mL) ?

[@elainegou]

ye

[@dontmindme4466]

the rounding could be done at the end. it wouldn't compromise the accuracy if you round all at the end.

How to get the mass if p value and volume is given? (this topic is under P function)

[@MoghlordOfblood-rc2lw]

Shouldn’t you have needed a new molar mass for the 2nd th yield in the last question? You used the mass of 2Na3PO4 instead of 3CaCl2 which is the molecule being used to calculate the mass

[@Pinkltonn]

So we always use the limiting reactant to find valuee in this kind of question Some one help Like wich one am i supposed to use and uow do i know if its limiting or not

You can just keep it mL if you want your answer in mL

[@zandilentuli7115]

@@krisssssssu thank you

[@emelye8504]

when your balancing, do you assign the coefficients through charges on the periodic table? Or oxidation numbers?

[@dontknow7863]

when you are balancing equations you need to have the same amount of atoms on each side. so for example: Fe + HCl >> H2 + FeCl2 = Fe 2HCl >> H2 + FeCl2, so now you have 1Fe atom on each side 2H atoms on each side and 2Cl atoms on each side.

For the mL or L you can do as you please so long as the question asks for either. For m1v1=m2v2 I'm not really sure, but the reactant ratio should have an effect on that formula.

[@jennyritz4611]

Ok, would people please stop teaching students to use M1V1=M2V2 for everything? Doing a separate mole ratio step works every time, and most of the time students won't remember to incorporate molar ratios into the ***DILUTION*** equation. It's for dilutions only, and after 9 years of seeing the same mistakes, I wish it would stop being perpetuated, especially by popular KZbin tutorials.
