2H2 + O2 = 2H2O is a neutralization or non-neutralization reaction? And explain why..
Gemiola [76]
This is a neutralization reaction since, the hydrogen ion, H+, from the HCl is neutralized by the hydroxide ion, OH-, from the KOH to form the water molecule, H2O and salt, KCl only.

What is colligative property? why does theproperty changes the way that it does when the amount of solute is increased. State an
elena-14-01-66 [18.8K]

Colligative properties are those substances that depend on the number of substances in the solution, not in the identity of that substance. The property changes the way that it does when the amount of solute is increased because it enables the solute to be scattered more. For example, the freezing point of salt water is lower than that of the pure water due to the salt ions present in water.

The amount of I₃⁻(aq) in a solution can be determined by titration with a solution containing a known concentration of S₂O₂⁻³(aq
puteri [66]

Answer: 0.22 M

Explanation:

2S_2O_3^{2-}(aq)+I_3^-\rightarrow S_4O_6^{2-}(aq)+3I^-(aq)

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{moles}{\text {Volume in L}}

moles of Na_2S_2O_3=Molarity\times {\text {Volume in L}}=0.440\times 0.025=0.011moles

Na_2S_2O_3\rightarrow 2Na^+S_2O_3^{2-}

Thus moles of S_2O_3^{2-} = 0.011

According to stoichiometry:  

2 moles of S_2O_3^{2-}(aq) require 1 mole of I_3^

Thus 0.011 moles of S_2O_3^{2-}(aq) require=\frac{1}{2}\times 0.011=5.5\times 10^{-3} moles of I_3^-

Thus Molarity of I_3^-=\frac{5.5\times 10^{-3}}{0.025L}=0.22M

Therefore, the molarity of I_3^- in the solution is 0.22 M
