Answer:
i pretty sure it decreses
Explanation:
Well. There is the color change and the formation of bubbles.
Answer:
bruh, just go in your bathroom and look for cleaning products
Explanation:
<span>Well # # Drops of Iron Sulfate # Drops of Sodium Hydroxide
</span><span> A1 5 45
A2 10 40
A3 15 35
A4 20 30
A5 25 25
A6 30 20
B1 35 15
B2 40 10
B3 45 5

<span>that's for B, because it says "Iron Sulfate".
which is this equation:
FeSO4 (aq) + 2NaOH (aq) Fe(OH)2 (s) + Na2SO4 (aq)
</span>
<span>FeSO4 (aq) + 2NaOH (aq) Fe(OH)2 (s) + Na2SO4 (aq)
ratio of FeSO4:NaOH is 1:2,
so you need to moles of NaOH for every mole of FeSO4.
</span>
<span>A1-A6 had precipitate, though less ppt every time.
This corresponds to the decrease in the number of NaOH drops
At A2 10/1:40/2 the stoichiometric ratio is equal, so you should've seen the post ppt present. But looking at the picture it doesn't look right. I think you might've labelled them wrong, or there is an error somewhere. This fits micro-plate A better.</span><span>
