What is the silanol surface density of freshly cleaved mica in RT? With approximation I found out it to be 1 Si-OH / nm^2. Is this value reasonable?

In mica 11% surface Si atoms carry -OH groups according to literature.

Is it possible for the soil pH to be around 8, but with negligible amounts of carbonates, bicarbonates and exchangeable sodium?

Can this pH of 8 be due to the presence of other substances? Or do I have an error somewhere in the analysis? Thank you!

What is mica? What conjugation chemistry are you using?

Thiranjeewa Lansakara

Mica is a mineral ( a poly alumino silicate) which can be purchased as chips. They are atomically flat layers which can be peeled off. When functionalities with ethanolamine hydrochloride it forma a Si-O-C bond between mica and ethanolamine.

Mohammad Mahbubul Hassan

Yes, pH play role. The reaction should be carried out at the alkaline side of the pH.

But in literature it's mentioned that in alkaline medium the Si-O-C bond will be cleaved. I thought slightly acidic medium would help.
