Answer 2

Ok so what part do you need help with? Because the instructions are clear.

Answer 3

Im have the hard time trying to sort out the number for question2

Answer 4

@wolfe8

Answer 5

How did the experiment go?

Answer 6

i still feel like i did i wrong but im not sure

Answer 7

how much do i put for each of the solution again?

Answer 8

Number for what? In the solution column you just put in which of the 2 reactants you use is which.

Answer 9

HCI and NaCI

Answer 10

how mush do i put in>

Answer 11

I think that's the first one. The second one is 2NaOH + H2SO4 → Na2SO4 + 2H2O no? This is why it's hard to help with projects and labs because you're the one who does the lab. We can only guide you.

Answer 12

oh ok so2NaOH + H2SO4 → Na2SO4 + 2H2O is #2 than what do i leave in the chart?

Answer 13

im srry im taking your time on this, i really thank you for helping me

Answer 14

Well which one is the base which one is acid? Molar ratio can be obtained just by looking at the balanced equation; take a look under the equation.

Answer 15

naoh is the base and hci is the acid i believe

Answer 16

Well again, are you asking for the first one or second one?

Answer 17

omg im lost now

Answer 18

lol :P

Answer 19

ok lead me thoug the first one then i have me understand better

Answer 20

Ok well look at the end of your fourth page. Those are your equations for questions 1 and 2 if I understand correctly. Only you will know for sure since YOU'RE the one who did the lab.

So now for the first one you will decide which is which from the first equation.

Answer 21

Answer 22

Yes

Answer 23

Answer 24

Yes

Answer 26

Answer 27

Like I said, in the solutions column which is which. Molar ratio is given.

Answer 28

below the answer for the first qutsion said "mole ratio of acid to base is 1:1"

Answer 29

Hmm wait. Mole ratio and molar ratio are different. Molar is the concentration in moles/L. What concentration did you use?

Answer 30

mine said unknown M

Answer 31

yeah , i didnt do it right :/

Answer 32

What info DO you have? This is really hard for me to explain to you from my side :/

Answer 33

this is what i hvae

Answer 34

@wolfe8

Answer 35

Ok so you have the concentration for NaoH. You can find concentration for HCl using the method on page 3.

Answer 36

but shouldnt my concentration be 0.1?

Answer 37

@wolfe8

Answer 38

I don't know. You'll have to use the final volumes at the end of the titration

Answer 39

how did you get it?

Answer 40

You do the lab till the end...

Answer 41
