Ionize Hydrogen and Oxygen Gas in Electrolytic Cell?
As is well known, water can be electrolyzed into oxygen and hydrogen gasses. However, all redox reactions can be run in reverse. If I were to electrolyze water in 2 closed containers (in order to trap ...

Does iron(III) sulfate react with copper?
As my understanding, there should be an oxidation-reduction reaction:
$$
\ce{2 Fe^3+ + Cu → 2Fe^2+ + Cu^2+}
$$
However, I always see the process using $\ce{FeCl3}$ to etch copper, but I never ...

What happens when oxidizing Ni(OH)2 with a strong base?
In an aqueous solution, Nickel oxyhydroxide is oxidised with a 1:1 ratio of aqueous Sodium hydroxide. My goal is to produce Nickel oxyhydroxide ($\ce{NiOOH}$).
Strong Base: $\ce{NaOH + H2O \...

Is there a database which give reaction constant?
For instance, I have a chemical reaction like :
$$\ce{Fe^{2+} + $0.5$O2 + H^{+} ->Fe^{3+} + $0.5$ H2O}$$
And I would like to use Action-Mass law, but I need to have equilibrium constant for this ...

Can lead(II) oxidize tin metal in aqueous solution?
According to my textbook, element $\ce{X}$ can oxidize element $\ce{Y}$ if $\ce{X}$ was lower in the activity series.
Lead is lower than Tin in the activity series table in the textbook, but the ...

In a redox reaction, why does more than one oxidation state of an element form?
Consider the reaction 100ml 10M $\ce{NaOH_{(aq)}} +$ 100ml 10M $\ce{NaHSO3_{(aq)} +}$ 100mL 0.01M $\ce{KMnO4_{(aq)}}$
In the picture posted here, the left columns give information on the Molarity of ...

Electrolysis of aqueous copper (II) nitrate
There are two copper blocks sitting in the $\ce{Cu(NO3)2 (aq)}$ solution, a battery is attached onto both of them, providing enough energy to start the reaction.
Since solid pieces of copper are ...

How would I calculate the Normality of a 0.00167 molar solution of KIO₃?
I need a 0.01 N solution of $\ce{KIO3}$ to use as a standard in a Winkler titration. The protocol that I am using specifies that this is 0.3567 g L-1, which I have calculated to be 0.00167 M based on ...
