Yes. That's correct. I digged myself deeper in this question and find some useful information about that. It says that rivers flow near mountains and through forests and therefore the chance is bigger that alkaline metals that is normally stored underneath the ground can be transferred to river wate...

Alkalinity
Hello! I have a question about the alkalinity of three water samples. I did a titration experiment where I firstly titrated seawater , secondly river water and lastly tap water with HCl. I used a color indicator as well in order to see the equilibrium point. Anyways this is what I got : Alkalinity f...

Thank you very much for your answer. As I said the products were given in the question so I had to follow the instructions. Anyways I have got a balanced equation and based on that I tried to calculate the mass of CO2. I would be grateful if you could have a look at my solution :). OBS! I used the d...

Redox reaction
Can somebody out here help me with this redox reaction? it says that KMnO4 reacts with K2C2O4 in acidic conditions and the products are MnO2 and CO2? this is how I did it: [KMnO4 + (4H+) + (3e-) -----> MnO2 + (K+) + 2H2O] *2 [K2C2O4 ------> 2CO2 + (2K+) + (2e-) ] *3 ________________________ 2KMnO4 +...
