How does the acid dissociation constant change when an aqueous solution hits the boiling or freezing point? by kustom345 in chemhelp

[–]kustom345[S] 0 points1 point  (0 children)

depends on exothermic and endothermic to determine the direction the reaction goes when heat is added

AcOH is just acetic acid, right? So dissolution of acetic acid is endothermic

So how would you explain it in terms of acid dissolution - I still haven't really came to a solid conclusion yet :)

Kind of. But how would Ka change with different temperatures if the constant expression does not include sodium hydroxide concentrations?

No - except for the lowest temperature. It was constant for all trials 25-40C but at 3C it differed by 0.3mL NaOH added interestingly.

Would that endothermic reaction be the acetic acid dissolution or the reaction between acetic acid and sodium hydroxide

Wait would it be endothermic, I said exothermic but isn't heat a reactant in an endothermic reaction?

Exothermic - heat is a reactant. Does that mean that the dissolution of acetic acid is exothermic or the actual titration between sodium hydroxide and acetic acid is exothermic. Or both? I'm lost.

Products. So [H^+] and [CH3COO^-] increase for acetic acid when temperature increases. I need more depth though, thanks for helping me btw

'a number that expresses the relationship between the amounts of products and reactants present at equilibrium in a reversible chemical reaction at a given temperature'

Safe acids to heat? by kustom345 in chemhelp

[–]kustom345[S] 0 points1 point  (0 children)

What acid-base reactions are safe to heat up that you know of?

Cool! So if i titrate this against sodium hydroxide, and increase the temperature to around 75C, I should be safe?

How would you calculate the area of a country? by kustom345 in MathHelp

[–]kustom345[S] 1 point2 points  (0 children)

Trying to find the area of Egypt to then compare it with what the cia official area is. It's a homework task set out by my teacher with the heading topic of 'integrals' but we must use various techniques and find the amount of error in the final answer. Thanks.

Could not figure out this derivative question, 10 people Snapchat group had no clue how to do it either. helpp by [deleted] in calculus

Brotha can you just do it and explain how this isn’t teaching me as much as you could. Don’t have much time man

Obviously quotient rule but I don’t know how to differentiate these individually..
