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.
Explanation:
What happens when chlorine form an ion is that it gains an electron and has an octet in its outer shell ( answer A)
<u><em> Explanation</em></u>
<u><em> </em></u>Chlorine is is in atomic number 17 in periodic table.
The electron configuration of chlorine is 1S2 2S2 2P6 3S2 3P5 or[Ne]3S2 3p5 or 2.8.7.
chlorine therefore has 7 valence electron therefore it gain 1 electron to form Cl- ( ion)
Cl- has 8 electron in its outer shell ( it obeys octet rule of eight valence in outer shell.
<span>Unless otherwise stated, the common room
temperature and pressure is at 25°C and 1 atmosphere, respectively. At this
temperature and pressure hydrogen chloride is expected to be in a gaseous state.
Since it is a diatomic molecule consisting of hydrogen and chlorine atoms, they
have weak forces of interaction between molecules resulting to an uncondensed
state at room temperature. If the atmosphere where is it suspended has
moisture, hydrogen chloride gas is expected to react with the moisture to form
fumes of hydrochloric acid.</span>
