Bu ramziy rasm nemis monaxi (rohibi) Bazil Valentinning 1599 yilda nashrdan chiqarilgan "Bazil Valentinning o'n ikki kaliti" ("Twelve Keys of Basil Valentine") falsafiy-ilmiy kitobining uchinchi kalitida (III BOB) keladi. Bu kitob o'sha paytlarda alkimyogarlar tomonidan ilgari surilayotgan mashxur "Falsafa toshi" ilmiy-izlanishlarini tartibli shaklda yoritib bergan. O'sha davrlarda oltin metallarning shoxi deb qaralgan. "Falasafa toshi" falsafasining asosini istalgan metallni oltinga aylantirish yo'nalishidagi ilmiy izlanishlarni o'z ichiga olsada, shu davr olimlari uchun oltinni ham erita (yo'q) qila oladigan qudratli eritma borligiga ishonishgan va izlanishgan. Ana endi ko'pchilik kutgan savolga javob bersak. Bu rasmdagi ramziy ma'no shundaki, metallar shohi oltinni ham erita oladigan qudratli kuchli eritma borligini aks ettiradi. Ya'ni, orqadagi qasr go'yoki oltin, undan oldinroqdagi kichik uylar, ikkinchi darajali metallar (mis, kumush, temir kabi). Tulki tovuqni olib qochyapti, xo'roz esa tovuqni qaytarib olish uchun hujum qilyapti. Ya'ni bu, o'sha davrda oddiy uylardagi tovuqlarga tulkining hujumi borligi, kimyoviy tilda esa ikkinchi darajali metallarni erita oladigan suyuqliklar (kislotalar) borligini anglatadi. Eng oldidagi fonda esa qasrga hujum qila oladigan kuchi va qo'rqinchli shaklda tasvirlangan bahaybat mahluq (ajdarho) aks etgan. Uni tepalikka chiqa oladigan qanotlari va qasr devorlarni yo'q qila oladigan og'zida nayzali quroli bor. Bu degani kimyoviy tilda oltinni ham erita (yo'q) qila oladigan kuchli eritma borligini tasvirlaydi. Bugungi kunda bu "shoh arog'i" yoki "zar suvi", ya'ni zamonamizdagi 3HCl:1HNO3 nisbatdagi eritmaning oltinni erita olishini anglatadi. Au+3HCl+HNO3=AuCl3+NO+2H2O
(yoritib beruvchi: ustoz Bunyod Raxmanov)

qoshimcha: zamonaviy talqinda biroz o'zgartirish kiritildi, ya'ni oltinni eritish uchun 4HCl:1HNO3 nisbati kerak bo'ladi:
Au+4HCl+HNO3=H[AuCl4]+NO+2H2O

👀Aksari elektroliz masalalariga, xatto nazariy savollariga e'tibor bersangiz F ni Farad deb yozishyapti. O'rgatuvchilarning aksari ham Farad yoki Faradey ahamiyatsizday istaganini aytib tushuntiryapti. Sababki, "Farad" va "Faradey" tushunchalarini farqlay olmaslik hamda e'tiborsizlik, ammo bu katta xatolik! Xullas, bu tushunchalar mutlaqo boshqa ilmiy tushunchalarga ega. Quyidagi videodars orqali buni anglab yetasiz...
