In addition, the effects of solvents and molecular structure upon acidity compounds 1-9 were also determined and discussed. The half-neutralization potential values and the corresponding pKa values were determined by half neutralization method.</dc:description><dc:date>2021</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/18677</dc:identifier><dc:identifier>https://doi.org/10.51435/turkjac.940613</dc:identifier><dc:language>en</dc:language><dc:relation>Turkish Journal of Analytical Chemistry (Online)</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/18677</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
