Natural plant extracts have garnered significant attention in recent years due to their diverse chemical compositions and potential applications in various scientific fields. This study explores the utilization of these extracts as acid-base indicators, offering an eco-friendly alternative to synthetic indicators. By harnessing the inherent pH-sensitive properties of plant compounds, particularly anthocyanins, this research aims to determine their pKa values, crucial for understanding their behavior in acid-base reactions. Through spectrophotometric analysis, the absorbance changes of plant extracts across a range of pH levels are examined, allowing for the identification of their pKa values. The experimental findings elucidate the efficacy of natural plant extracts as indicators and provide valuable insights into their potential applications in analytical chemistry and beyond.
Tabiiy o‘simlik ekstraktlari so‘nggi yillarda turli xil kimyoviy tarkibi va turli ilmiy sohalarda potentsial qo‘llanilishi tufayli katta e'tiborni tortdi. Ushbu tadqiqot ushbu ekstraktlardan sintetik ko‘rsatkichlarga ekologik toza alternativani taklif qiluvchi kislota-asos ko‘rsatkichlari sifatida foydalanishni o‘rganadi. O‘simlik birikmalarining, xususan, antosiyaninlarning pH-sezgir xususiyatlaridan foydalangan holda, ushbu tadqiqot kislota-asos reaktsiyalarida ularning xatti-harakatlarini tushunish uchun muhim bo‘lgan pKa qiymatlarini aniqlashga qaratilgan. Spektrofotometrik tahlil orqali o‘simlik ekstraktlarining pH darajalari oralig‘ida absorbsiya o‘zgarishlari tekshiriladi, bu ularning pKa qiymatlarini aniqlash imkonini beradi. Eksperimental topilmalar tabiiy o‘simlik ekstraktlarining ko‘rsatkichlar sifatida samaradorligini aniqlaydi va ularning analitik kimyoda va undan tashqarida qo‘llanilishi haqida qimmatli tushunchalarni beradi.

В последние годы натуральные растительные экстракты привлекли к себе значительное внимание из-за их разнообразного химического состава и потенциального применения в различных научных областях. В этом исследовании изучается использование этих экстрактов в качестве кислотно-щелочных индикаторов, предлагая экологически чистую альтернативу синтетическим индикаторам. Используя присущие растительным соединениям, особенно антоцианам, рН-чувствительные свойства, это исследование направлено на определение их значений pKa, имеющих решающее значение для понимания их поведения в кислотно-основных реакциях. С помощью спектрофотометрического анализа исследуются изменения оптической плотности растительных экстрактов в диапазоне уровней pH, что позволяет определить их значения pKa. Результаты экспериментов проясняют эффективность натуральных растительных экстрактов в качестве индикаторов и дают ценную информацию об их потенциальном применении в аналитической химии и за ее пределами.
