Yes @Billzene is correct. Specifically in QCE, all you need to know is pKa in terms of titration graph (you need to know why as QCE can ask for an explanation) and the Henderson-Hasselbalch equation like Billzene said above. You'll also need to know how to calculate the Ka by using Ka=[H3O+][A-]/[HA] and then the pKa from it which is a simple -log.
Hope that helped.

purpleunicorn correct, the pKa is the halfway point between equivalence points, you see them as flat parts on titration curves since when pH = pKa, the buffer system is the most resistant to pH changes according to the Henderson-Hasselbach equation taught in uni chem (not sure if they teach it in QCE)
I’m so sorry…
kPa ≠ pKa .Thanks Billzene

pKa is actually the pH at which 50% of an acid is deprotonated eg since ethanoic acid's pKa is 4.74, at a pH of 4.74 you'd expect half of the species present to be unionised ethanoic acid (CH3COOH) and half to exist in the form of ethanoate ions (CH3COO-). It's defined as -log10(Ka), where Ka is the acidity constant i.e. equilibrium constant of an acid dissociation reaction- Edited

Howdy! I hope you don't mind me adding in a QCE perspective here lol.Basically, how our teacher taught us was that the thesis can be simple, as long as you follow HITS for the introduction.
H - Hook (a quote relating to the question, e.g. "Unsex me here!" (Act II))
I - Intro (introduction to the play e.g. Macbeth is a play written by Shakespeare, about a Scottish warrior who is led by ruthless ambition to commit regicide. (or something along the lines of that))
T - Thesis (It can be as simple as, "Shakespeare invites the reader to view the concept of masculinity as highly dangerous.")
S - Sub Arguments (This is evident through Lady Macbeth, who feels as though she must become more masculine to act upon her desires. Banquo and Macduff present the ideal male figure for the Elizabethan era and finally, Macbeth, whose misunderstanding of masculinity leads to his ultimate demise)You can also tie this in with ambition, as Macbeth through more ambition meant he was more masculine sorta thing.
Para 1: Lady Macbeth
2-3 quotesPara 2: Banquo and Macduff
2-3 quotes - talk about their loyaltyPara 3: Macbeth
2-3 quotesThe main way to approach a question is, if you get a character question, your three arguments are the themes.
If you get a theme question, your arguments are three characters that are very prominent in this theme.If you have any questions, just ask!

Ahhh... sorry
Also I should add I'm writing from the VCE perspective (so I may be barking up the wrong tree so to speak) - but is ur 'thesis statment' just a fancy way of saying ur contention/point of view?
If so - then that seems ok. Unfortunately you have a 'how prompt' which makes things harder (eg, we're doing a film in y12 - so we have to talk about how X uses point-of-view shots to immerse the reader in the film blah blah blah...)
Demonstrates isn't a great verb - as how can one 'demonstrate the concept of masculinity'? It doesn't really mean anything...Kinda just filler..
How about this:
A microcosm for belief's in the Jacobean era, Shakespeare's 'MacBeth' (underlined) explores the multifaceted aspects of masculinity. Through the play, he accentuates (highlights) the relationship between power and masculinity, and emphasises its desirability. However, he also warns of the consequences masculinity - how it can corrupt one's identity. Ultimately, Shakespeare contends that one needs a balance of both the masculine and feminine ideals to maintain their integrity.
Sor ur args are:
- masculinity, is desirable (because it provides power)
- it can corrupt ur identity (stepped in so far that should he wade no more.... can't wash blood clean from these hands, etc..)
- U need a balance of both masculinity & femininity.
Hope this helps ; )

Did Macbeth in y10, so I’m not too much help on that side of things… but the gist of English is actually quite simple. I really wish someone told me this wayyyy earlier.
You want to come up with 3-4 big statements the author is making about society. Lit calls these ‘views and values’ (v&v) - but I like to call them arguments.
U then use these for each paragraph. So instead of talking about characters, or things that happen, u make the first sentence the overall argument. Then use the events/characters as evidence…
Eg.
Point 1: Masculinity is considered desirable in society. Shakespeare presents this notion through the actions of Lady MacBeth. As she is realistically powerless, she becomes more masculine to become powerful…. Etc Expand on the idea a bit. Fit Macbeth in here too.
Thus power, associated with masculinity in patriarchal society’s, is held by men, but can be adopted through the actions of women.Point 2:
So on and so forth….Hope this helps!
It’s weird. It’s not ur opinion. But it’s ur opinion on what the author’s opinion is…. (I think shake spear thinks society should…. Except it’s in formal writing)
P.S: I can’t remember what Shakespeare actually says about masculinity, nor do I share these views. I’m just rambling about structure. (Women don’t have to be masculine to be powerful)
