C and A because the product of a matter will always be the same and just google A.
Answer:
<h2>10.03</h2>
Explanation:
The pH of a solution can be found by using the formula
![pH = - log [ {H}^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7BH%7D%5E%7B%2B%7D%20%5D)
From the question we have
We have the final answer as
<h3>10.03</h3>
Hope this helps you
Answer:
6 mols HCl
Explanation:
(I'm an AP chemistry student but not perfect at this stuff)
you can use the Molarity=Moles/L equation here:
(6M)=(moles HCl)/(1L)
divide by 1 on both sides to isolate the moles of HCl
this gets you 6 moles HCl.
Again I'm just a student so my answer might be wrong, but this question should just require the M=mols/L equation :).
It is important in gravimetric analysis to add an excess amount of precipitating ions to a solution containing an analyte because it helps to determine the mass of the analyte.
<h3>What is Gravimetric analysis?</h3>
This is a method which is used in the determination of the quantitative determination of the ion being analyzed(analyte) based on its mass.
Adding an excess amount of precipitating ions to a solution containing an analyte will make it easier for the mass of an analyte to be determined.
It is also important for the precipitate to be a pure substance with a definite and known composition which therefore makes it the most appropriate reason.
