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.

Professor Organic Chemistry Tutor, this is another outstanding video/lecture on solving Stoichiometry problems in AP/General Chemistry. Although the problems are similar, writing the Chemical Equations and solving them can be problematic from start to finish. This is an error free video/lecture on RU-vid TV with the Organic Chemistry Tutor.

@thirisharadhakrishnan5341 4 года назад

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 Год назад

Yup he got that one wrong

@starjumperrr 9 месяцев назад

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

@aprilreighntayag4316 4 года назад

Thank you for existing

@awkwardkoreanboy 6 лет назад

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 6 лет назад

awkwardkoreanboy no either way works

@Eyeh8t3leyef3 Год назад

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 Год назад

Very late😂😂

@TheLucanicLord 4 месяца назад

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.

@peacewonder1856 5 месяцев назад

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

@yishaogu4936 4 года назад

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 2 года назад

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

@emelye8504 3 года назад

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

@dontknow7863 3 года назад

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.

@anissgacem4362 2 года назад

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 6 лет назад

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 RU-vid tutorials.
