Title: Investigation of the pH-value of silicic acid in the presence of compressed CO2
Authors: Nguyen Hong Chi Vi 
Keywords: PH-value;Silicic acid;Compressed CO2
Issue Date: 2023
Abstract: 
This thesis documents the design and construction of a high-pressure view cell designed to allow observation of the pH change of silicic acid under compressed CO2. Additionally, this thesis also covers trial experiments using the high-pressure view cells. After the trials, the results are reviewed and discussed. The idea of this thesis is that after observing the pH change of silicic acid, data can be retrieved to create H+ ions concentration-distance profile of the acid. This profile is then used in conjunction with the error function to determine the coefficient of diffusion of CO2-silicic acid systems. Due to the complexity of such calculations, the calculations of the diffusion coefficient are omitted in this thesis. Based on the work done by this thesis, in the future others could replicate and go on further with the calculations
