Why and how do aqueous silica systems precipitate and can its occurrence be mitigated by quantifying its speciation correctly?
Background/Context:
For context, I have been doing a lot of work on experimental systems in geopolymer chemistry lately with a focus on "activator" solutions which are essentially mixtures ...

Why does this acid-base reaction occur?
My teacher told me about the reaction of sodium peroxide with water:
$$\text{Na}_2\text{O}_2 + 2\text{H}_2\text{O} \ce{->} \text{H}_2\text{O}_2 + 2\text{NaOH}$$
Now, the concentration of products ...

Reaction between barium peroxide and hypochlorous acid
When $\ce{BaO2}$ reacts with $\ce{HClO},$ the question tells us that that oxygen, barium chloride and one other product is formed.
The equation I came up with is
$$\ce{BaO2 + 2 HClO -> BaCl2 + 2 O2 ...

Can a weak acid react to give a stronger acid? [closed]
I was trying to understand why $\ce{AgCl}$ does not dissolve in $\ce{HNO3}$ and the reaction I could think of was something like this:
$$\ce{AgCl + HNO3->AgNO3 + HCl}$$
I could not understand why ...

Reaction of copper with nitric acid [duplicate]
When copper reacts with dilute nitric acid,
$$\ce{3Cu + 8HNO3 -> 3Cu(NO3)2 + 2NO +4H2O}$$
while with concentrated nitric acid,
$$\ce{Cu + 4HNO3 -> Cu(NO3)2 + 2NO2 + 2H2O}$$
As we see that with ...

Why does hydrolysis of OF2 give a neutral solution?
I found this equation on the internet for the hydrolysis of $\ce{OF2}$: $\ce{OF2 + H2O -> HF + O2}$. So, according to me, $\ce{HF}$ must make generate an acidic instead of neutral solution.
But ...
