๐Ÿ‘†yuqoridagi test mantiqan chalg'itishga asoslanib, kislota negizi va kislota kuchini solishtirish va anglashni taqozo etadi. Kislota kuchi o'zi nima โ€” eritmada proton yoki H+ ionlarining erkin mavjud bo'la olish darajasidir. Kislota kuchi faqat o'zidan H+ ni ajratish (dissotsilanish) darajasi bilan o'lchanmaydi, balki qayta anion bilan birikish (assotsilanish) darajasiga ham bog'liq bo'ladi. Assotsilanish darajasi qancha kichik bo'lsa kislotalik kuchi shuncha yuqori bo'ladi. Deylik, solishtirilayotgan kislotalar uchun dissotsilanish darajasi const bo'lsin, demak, kislota kuchi assotsilanishga bog'liq bo'lib qoladi. Assotsilanish o'z navbatida kislota qoldig'ining H atomidan olib qolgan elektronni barqaror holatda o'zida mustaqil saqlay olishiga bog'liq (orbital sig'imi). HI va HBr lar nega eng kuchli kislotalar hisoblanadi, chunki ularda assotsilanish darajasi juda kam va shu tufayli eritmada erkin ionlar salmog'i nisbatan ko'p bo'ladi.
