Answer:
Ok, so the goal of a titration is to figure out the concentration of the NaOH solution by seeing how much acid it takes to neutralize the NaOH solution. NaOH is a base, you want to neutralize it with an acid. The best acids to use would be a strong acid.
Some good choices would be hydrochloric acid, hydrobromic acid, hydroiodic acid, perchloric acid, nitric acid, or sulfuric acid. In reality, though, you could use pretty much any acid you wanted to.
Oh, and you should probably also add an indicator to your solution so that you know when your titration is done. In this case, a good choice would be phenolphthalein because it changes color right about pH of 8.

Answer:
The color of the solution turned a clear brown sort of a copper color
Explanation:
The color of the solution turned a clear brown sort of a copper color.
This is because ASA and the FeCl3 are reacting in a manner that it is resulting in the creation of a metal.
It true I jus answered it and got it right
<span>V = 150.0 mL = 0.15 L
c = 1.70 M
</span>m=?
For the purpose, the equation for molar concentration is necessary:
c=n/V
From the equation we can determine the number of moles:
n= cxV = 1.70M x 0.15L = 0.255 mole
Now we can calculate the mass:
m = nxM = 0.255 x 119= 30.34 g is necessary
Answer:
2NaOH + 2Al +2H2O = 2NaAlO2 +3H
Explanation:
Aluminum is an amphoteric element it reacts with both bases and acids to form a salt and hydrogen gas.The reaction is highly exothermic.
