titration related to the periodic table
« on: February 18, 2018, 02:02:05 PM »
I've got an assignment due soon. I really struggle with chemistry and I have to explain how titration is related to the periodic table.

any help would be amazing thank you!

Seems a bit vague, but any ideas on how to start?

i did a titration to find an unknown solution, i needed to calculate the mortality, but its asking me to relate it to the periodic table.

This is really an obscure way to teach people these concepts.  Its like needing the formula for the glass that makes up a text tube to describe a reaction inside it.  But we're here to help, and we have to try.

Describe the titration you did.  And tell us something you know about how we use the periodic table.  And maybe we can find something in common to work with.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

mortality,

Its called molarity unit mole/Volume or in other cases molality mole/mass

i did a titration of hydrochloric acid with sodium carbonate.
the aim of this experiment is to make a standard solution of sodium carbonate and then use it to find the molarity of an unknown hydrochloric acid solution.

it is asking me 'Relate the key features of the periodic table to the conclusions drawn from the practical activities'
I have no idea where to start

It is a forum rule (see red link) that you must give your thoughts before we can help you.  I will acknowledge that the question seems a bit vague at first glance.  You might start with a balanced equation.

What data/numbers did you use in your calculations?

(I agree with Arkcon, if the question means what I think it means it is very poorly asked, if it means anything else - it is even worse).

   Final volume   Initial volume
Rough    10.80   00.0
1           8.50            00.0
2           9.10         00.0
3           6.30          00.0
4           7.00         00.0
5          7.00           00.0

ive understood that i needed to use the mass of the sodium carbonate and hydrochloric acid to work out the formula mass etc, but how can i explain that i used it. i need to explain it in a big paragraph.

work out the formula mass

That's the only important thing here, and the only connection with the data usually presented in the periodic table.

Note: I was careful with wording. I have not referred to the "periodic table" but to the data it typically contains for a reason. Data required - atomic masses - are not the most important thing about the periodic table, they could be easily presented in any other kind of table (say, alphabetic list of elements). Periodic table is built around the fact element properties change in a periodic manner, which reflects their electron configuration (and its periodicity). Atomic masses do grow in the periodic table (if you know in what order to read it), and they did play some small role in the periodic table formulation, but they are not a necessary part of the table.

Relationship between titration and periodic table is a bit similar to the relationship between a car and the road map - you can't say there is no link at all, but to discuss this link you have to ignore the most important properties and applications of both car and the map.

I know I am not helpful, but the question seems quite poorly asked and quite difficult to answer in a reasonable way.
