paper 1最難應該係electrolysis H2SO4同果舊organic compound HA->A- + H+果舊 indicator黎
1:49xxx?
49xxx: 1
佢係問HA to A-
係 個陣都心諗伏到你
唔算好伏啦,寫到明既

係 大約50000:1
HA>>>>A-
點計 完全諗唔到
pH=-log[H+]
K=[A-][H+]/[HA]
我係咁做。。。。點解出唔到依啲答案

electrolysis of H2SO4 有咩難?
轉咗H2SO4有冇change in observation?

Suppose b 有gwa
1. More air bubble
2. 我寫左粉紅色範圍細左

條題目係點
有冇數字
就咁睇好數學

EAA唔似會出2.呢d 答案

竟然俾晒提示話order of reaction唔一定整數
