    Find the pH of a 10-7 mol l-1 H2CO3 Solution: Explained

    I was looking at the page on pH about 4 pages back thinking that's all there was, many thanks. Who are you by tyhe way?

    Find the pH of a 10-7 mol l-1 H2CO3 Solution: Explained

    Hi Borek the pure water was just given as an example not as a question. The question was to figure out the pH of H2CO3 to 10-7 mol l-1. I think that its an equilibrium as that's what we have been learning and I would imagine that it dissocociates to H+ and HCO3-. Sorry if I don't sound very...

    Find the pH of a 10-7 mol l-1 H2CO3 Solution: Explained

    Ok so i have this question to figure out. What is the pH of a solution having an H2CO3 concentration of 10-7 mol l-1?Now here is the info I've been given to learn about pH in my lecture notes. That pH is the negative log to base 10 of the concentration of hydrogen ions in a solution. It says...

    Help with a chemical equation please

    Ok Thanks, but i was told by my chemistry lecturer that we were fine using fractions so i will submit it like that and see what feedback i get. But thanks again for your help.

    Help with a chemical equation please

    Hey Thanks decided to have a go and just balanced it , think its this Ca3Al2Si3O12 + 6H2CO3 + H2O -> 3Ca2+ + 0.5Al4Si4O10(OH)8 + H4SiO4 + 6HCO3- Seems to be correct, I had'nt realized the coefficient on the charged ions needed to be that way, but it makes sense. You've made my christmas...

    Help with a chemical equation please

    Thanks did'nt expect a reply today, but will take your advice on board and have another crack at it , although that probably won't happen until all the turkey and wine has been finished. Many thanks and a merry christmas to you.

    Help with a chemical equation please

    Hi I'm new on here and a mature student studying geology. We have an assignment (our 5th one) to be in on the 11th jan . I'm in my 1st yr and have not ever studied chemistry unless you count a couple of years around the age of 11 or 12 which was now roughly 28 yrs ago! Anyway I've been trying...
