A scientist needs to check several parameters before coming to a conclusion about the amount of water pollution. The scientists needs to check the amount of dissolved oxygen in the water, temperature of the water, the clarity of the water, the PH level of the water and also the amount of bacteria present in the water. There may be other criteria’s, but the mentioned ones are enough to gauge the amount of pollution in the water. Scientists often takes fish and aquatic plants from the water to be tested to check the amount of pollution indirectly affecting these species.

Chemistry help on a Lab I did ?

<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

</span>
<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>
