What is meant by 'as Cl2'
In general, sentences like "The concentration of X as Y is z mg/L" should be interpreted to mean "If you extract all the X from 1 L of solution, then convert the X completely to Y (...

Which of the following might turn NaNO2 into N2?
To get N2 from NaNO2, NaNO2 must be reduced right, So we need a reducing agent which oxidizes itself and would reduce NaNO2
Now look at the options
Let's see HNO3, the oxidation state of Nitrogen is ...

What causes ionisation in redox reactions?
The fundamental mistake you're making here is treating each atom in the reaction as though it's isolated. If you do that, the reaction will make no sense. You have to look at them together.
The energy ...

What is meant by 'as Cl2'
Let imagine there are 3 bank accounts, one with 10000 Euros, one with 10000 US dollars, one with 10000 UK pounds. Let assume - just illustratively - there is exchange ratio 5 dollars per 4 Euros and ...

Acid dissociation constant from conductometric data
The molar conductivity $\Lambda_\ce{AHCl hydr}=\pu{119.4 S cm2 mol−1}$ is equivalent to the partially hydrolyzed hydrolyzed anilinium chloride, according to the hydrolysis constant.
$$\ce{PhNH3+(aq) + ...

Why does the reaction "pause" when the battery is not connected to a circuit? (or does it?)
In a battery, the zinc and manganese reagents are kept separate, and so the electrons can only flow when both parts of the battery are connected via an electric circuit.
If you take a look at the ...

Why does the reaction "pause" when the battery is not connected to a circuit? (or does it?)
If no wire is joining the zinc plate and the $\ce{MnO2}$ plate, the whole setup would not be a cell or a battery. It wouldn't produce any anode or any cathode. The whole setup would simply be a ...

is alkyl halide turning into alkene reduction or oxidation?
HI is being removed in the reaction. It is $\beta$-elimination. I really am not able to see any changes in the oxidation numbers also.
$\ce{CH3-CH(I)-CH2-CH3}$ will undergo dehydrohalogenation.
Only ...

Acid dissociation constant from conductometric data
This answer is more about the chemistry and how the conductivity relates to the ions present, and does not show a numerical solution. For that, check the answer by Poutin.
Here is the acid/base ...
