An end point is the point where the indicator or phenolphthalein changes its colour. An equivalent point is the point where the mol or quantity of acid and base is equal. 4. Why did the solutions turn pink ...
In this chemistry experiment, you'll be learning how to find the concentration of an acid using titration with a weak base. By the end of this experiment you'll understand more about chemical reactions between acids and bases and the process of titration. ...

chromatography (HPLC, LC-2000 plus; JASCO Corporation, Tokyo, Japan), using the method described by Cai [22]. The LBC was measured by the titration method described by Muck et al. [23]. The sample pH was reduced to 4.0 using HCl, and then titrated with NaOH from pH 4.0 to 6.0 (...
Moisture content was measured via Karl-Fischer titration. The mono-layer sheet was extruded at the processing temperatures summarized in Table 3. The melt curtain was cast onto a cooling drum whose surface temperature was set at 25° C. to solidify the non-oriented laminate sheet. The non-...
