Study sets

Everything for the test.
Made from your material.

Say what the test is and hand Groply the material for it. It writes the flash cards, the study sheet, the quiz and the practice paper, then stays open to questions on every line of what it wrote.

What comes back

One set. Everything in it built from the same material.

Tick what you want and Groply writes it, from your notes rather than from a general version of the topic. They arrive as tabs along the top of the set, in the order you picked them.

Question

Why does a weak acid need more base to reach the equivalence point than its concentration suggests?

Click to turn it over

Answer

It does not. It needs the same moles.

Equivalence is about moles, not about how much of the acid has dissociated. The pH there is what changes.

Question 3 of 12

Titrating ethanoic acid with sodium hydroxide, which indicator should you use?

AMethyl orange, it turns at pH 3.7BPhenolphthalein, it turns at pH 8.7CBromothymol blue, it turns at pH 7.0DAny of them, the indicator does not matter

A weak acid against a strong base reaches equivalence above pH 7, so the indicator has to turn there. Methyl orange would have finished long before you got to it.

Every set you make stays in your account for good, on every plan including the free one. Nothing you have made is ever put behind a payment.

Ask it anything

Then it explains what it wrote.

Pick any line of any document in the set and ask about that line. Groply already has the material, so it answers on your notes rather than on the topic in general, and the thread stays with the set.

Weak acid titrations

Section 3 of 7

Adding a strong base to a weak acid does not give the sharp jump you get with a strong acid. The curve leaves the axis slowly, flattens through the buffer region, and only then climbs.

At half equivalence, pH equals pKa.

That is the measurement the whole experiment is for. Read the pH there and you have the pKa of the acid in the flask, to about a tenth of a unit.

Groplyknows this set

Ask about anything in this set. Or pick a line in the document and Groply will take it from there.

Ask about this set

Ask about one line without re-explaining the whole set
It can turn what you asked into more cards, or a question to answer
Come back next week and the thread is still under the document

The rest of it

Three more things, said plainly.

Named rather than demonstrated, because a page that animates everything is a page nobody reaches the end of. Everything above this line you can watch. Everything below it you can go and try.

CoursesHand over a term of material and get a lesson plan back: chapters, lessons under them, and a tick against each one as you finish it.

PodcastsNewAny set can also come back as an episode, two voices talking your material through, for the walk in or the bus.

Anything elseStudy is the front door, not the whole house. Put an essay, a problem set or some code that will not run on the bench and it comes back with the working attached.

Questions

The ones worth asking.

Is it free?

To start, yes. The free plan is 5 runs a day on the fast model. Paid plans lift the daily limit and put you on the stronger ones, and the sets you have already made are never affected by which plan you are on.

Does it just do my homework for me?

It writes the documents, and then it hands you the reasoning behind them, and then it tests you on it. That is a deliberate shape. Handing in something you cannot explain is a bad trade whoever wrote it, so the questions are not an optional extra you switch on: the quiz marks itself and tells you why, and the buddy will argue with you about any line of any document in the set.

What can I give it?

Lecture slides, a chapter as a PDF, your own typed notes, a photo of the whiteboard, a past paper. Say what the test is in the same box, and everything Groply makes comes out of what you handed it rather than out of a stock bank of questions about the subject.

What happens to what I upload?

It is stored against your account so you can come back to it, and the privacy policy says exactly what is kept, for how long, and how to have it removed. It is written in plain words rather than in the usual language, because a policy nobody can read is not a policy.

Do I have to install anything?

No. It runs in the browser you already have open. There is no download, and there is no extension that wants to read every page you visit.

Put the test in.

Whatever is coming up, and whatever you have for it. You will have the set back before you have finished making a coffee.
