Create a graph of pH vs. volume of added NaOH … WebDec 1, 2016 · So as we consume more and more HA (by adding NaOH) the H + on concentration decreases. An so the pH increases, But the amount of change in the pH, increases when it comes near to equivalence point and then again start to decrease so we can calculate the Equivalence volume of the titration.
WebFeb 22, 2024 · In recent years, many research efforts were spent in investigating the corrosion mechanism of steel reinforcements in alkali activated concretes and mortars, due to the carbonation that induces pH lowering [12,13,14] or due to the presence of aggressive species, especially chloride ions [15,16,17].Compared to OPC-based materials, … http://accounts.smccd.edu/batesa/chem220/lab/labmanual-sum12/9-ph-titration-sum12.pdf
WebJun 26, 2024 · The half-equivalence point is when just enough base is added for half of the acid to be converted to the conjugate base. When this happens, the concentration of H + ions equals the K a value of the acid. Take this one step further, pH = pK a . The second point is the higher equivalence point. WebJan 28, 2015 · The ground carbon xerogel (1 g) was suspended in an H 2 PtCl 6 aqueous solution (0.6 g Pt /L) for 1 h, at ambient temperature, under magnetic stirring. At the beginning of the impregnation, the pH of the solution was always about 2.2, due to the acidity of H 2 PtCl 6. After 24 h of magnetic stirring, NaBH 4 was added to reduce the Pt …
