Question

Briefly comment on the effect, if any, the following procedural changes would have on the observations.
NH3/H20
Experiment
blue litmus paper: had no color change, red litmus paper: turned blue, thymol blue: turned blue, methyl orange: turned orange yellow, phenolphthalein: turned magenta
Common indicators and their associated pH ranges
thymol blue: red to yellow 1.2-2.8, yellow to blue 8.2-9.1
methyl orange: red to yellow 3.1-4.4
phenolphthalein: colorless to red 8.0-9.8

Answer 1

(1) You poured 4mL of .1M NH3/H2O solution into test tubes #1 and #2, and 1mL of the solution in test tube #3. You added phenolphthalein indicator solution as directed.
(2) You poured 4mL of .1M NH3/H20 solution into test tubes #1 and #2, so you added 2mL H2O to the solution in test tube #3 to bring the total solution volume to desired 3mL.
(3) You added only 1 drop of phenolphthalein indicator solution to 3mL of NH3/H2O solution in test tube #3.

Answer 2

what the question

Answer 3

Briefly comment on the effect, if any, the following procedural changes would have on the observations, so (1), (2), and (3) I posted above your question. ^^

Answer 5

so the question

Answer 6

What would happen if i added phenolphthalein solution to the following information posted on (1), (2), and (3)

Answer 7

If the concentration of indicator is particularly strong, it can appear purple. ... When a base is added to the phenolphthalein, the molecule ⇌ ions equilibrium ... 1 Synthesis; 2 Uses; 3 Physiology; 4 See also; 5 References; 6 External links ....

Answer 8

So when I add 3 drops of phenolphthalein to 1ml of NH3/H2O instead of 3 drops of phenolphthalein to 3ml of NH3/H2O which I got a color change of purple, the 1ml of Nh3/H2O will still have the same color change as when I added 3 drop of phenolphthalein to my 3ml of NH3/H2O? Or would it be more of a darker purple

Answer 9

@micahm

Answer 10

yes

Answer 11

it would be a more darker purple or the same colored purple as when i added 3 drops of phenolphthalein to the 3ml of NH3/H2O?
