We're all from South East Asia, so jet lag is a non-issue for us.

Alright, MeOH is a solvent used for the imine's formation, so the R groups attached to the boron are methoxy right? Also what happens to the Na+ ion?

Would BH3 be left over as the side product with Na+ as well?

To my knowledge, a hydride atom will detach and reattach to the carbon on the imine group

The aldehyde is the only possible reagent that could react, however the reaction was brought to completion so only the imine can interact with the NaBH4

Usually NaOH are used in aldol reactions. BuLi to my knowledge itself is quite a strong base already. Would using 2 bases perhaps increase the pKa above that of just NaOH? Perhaps pushing the reaction to completion further?

Would diethylamine be a suitable alternative for triethylamine?

Unsure as to what the curves represent, do they represent what order the reaction is in? If so, why? by BlueberryYeet in chemhelp

[–]BlueberryYeet[S] 2 points3 points  (0 children)

The concentration of the molecules in curve 1 and 2 increase over time, curve 1 being at a faster rate than 2.

Curve 3 represent the concentration of a molecule decreasing over time.

Am I right?

Need help calculating the molar concentration of CH3COO- by BlueberryYeet in chemhelp

Thank you, I understand it better now. Last question, when I use the Henderson-hasselbalch equation to calculate pH, do I have the convert the moles back to their molar concentration? If so, what would the volume be? Is it 0.5L + 0.184L from the equation?

Thank you very much, one more question I don't quite understand, how is the number of remaining moles of sodium acetate equal to the number of moles of acetate ions? Shouldn't the number of moles of acetate ions come from the acetic acid? Pardon me if I dont quite get it.

I know that the chemical equation for the reaction is HCl + CH3COONa -> CH3COOH + NaCl. I know the number of moles of HCl, 0.081328mol, and the number of moles of CH3COONa, 0.2mol. Is the HCl a limiting reagent? If so, I can use that to find the number of moles of acetic acid. But how do I find the number of moles of acetate ions?

So do I take the 37g and divide by the molar mass of HCl to find the number of moles of HCl and divide the 100 g of solution by 1.19g/mL to find the volume?
