Question

When graphing.. and it says graph for example: Time verses Speed or pH verses log[HCl] ECT.

Is the Time or pH= y axis?

Answer 1

and.. speed or log[HCl] = x-axis?

Answer 2

usually when you plot time vs. speed, time goes along the x axis... Speed is a function of time (often), so speed is your y axis.

Answer 3

hmm..... okay but what if if someone is like.. graph flower vs soil?

Answer 4

what would be the y and the x??

Answer 5

It can be confusing... the way I think you are supposed to do it is to decide which variable depends on the other. The soil type is just what it is... but the flower's behavior in different soil types depends on what type of soil you put it in.

So the thing that depends on the other is the vertical y-axis... the flower height is y, and the dirt type is x.

Answer 6

another example: student height vs. age. Your age is just your age... but your height sort of depends on your age. So if you wanted to plot the height vs. age for all the students in a school, list height as the y-axis and age as the x-axis.

Answer 7

hmm.. okay D: I mean I have to graph.. pH vs log[HCl]

Answer 8

im putting pH as the y axis..hm

Answer 9

I'm less sure when you graph something with a log of one variable.

Answer 10

what is HCI in this example, anyway?

Answer 11

oh it is a strong acid??

Answer 12

the log of the.. the mole of the strong acid

Answer 13

It's probably Hydrogen Chloride, symbol HCl ( I thought that last letter was an I, but it's an L)

Answer 14

yeah, it's an acid. So the more you have, the lower the pH, or something like that, right?

Answer 15

hmm.. it's kind of weird but.. they're suppose to be similar to each other??

Answer 16

log[HCl] pH
-1.48148606 1.88
-1.958607315 2.24
-2.435333936 2.62
-2.913640169 2.98
-3.390405591 3.36

log[Acetic acid] pH
-1.48148606 3.22
-1.958607315 3.42
-2.435333936 3.65
-2.913640169 3.88
-3.390405591 4.05

Answer 17

that's technically what I have to graph...

Answer 18

confusing right? haha but.. whatever.. thank you for your help Jake!!

Answer 19

Ugh. That looks fun.

Answer 20

haha yeahh totally. I hate school.

Answer 21

Several graphs I found via google just now seem to show pH on the vertical axis

Answer 22

sorry... is this chemistry?

Answer 23

oh okay so.. I'm probably doing this right.. haha yeah I was asking at the chem place but.. no one was there to answer anything

Answer 24

why wont hurricane sandy give me a school free day D:
