question of the year個人覺得係
electrolysis use 1M H2SO4
同埋add NAOH to nitrophenol 個change
後者點解咁講?
正常eqm pos shift since H+ OH- reacts?

想問我paper 1 overall 6成的話
但Paper 2得40-50% 係咪會拉低我跌落3

想問轉咗用H2SO4嗰題有change?我見好似3分

唔係咁簡單
你wiki pH indicator
有條叫pH = pKa + log [A-]/[HA]既equation (以前AL會學)
係講indicator用
Standard enthalpy change condition 係咩 是但寫佐25度
但係fe2(so4)3 fe3+個mol唔係要乘2咩

咪 1:2 lor

你做既時候有無諗過
既然佢下面果題你知隻野係用黎做indicator
咁一日未用曬水入面d H+ 應該佢都唔會轉色住
Standard enthalpy change condition 係咩 是但寫佐25度
1 atm
25 c
如果係溶液就1 M

你做既時候有無諗過
既然佢下面果題你知隻野係用黎做indicator
咁一日未用曬水入面d H+ 應該佢都唔會轉色住
但如果加NaOH
明顯會令到杯水既[H+] <<<< [OH-] after equilibrium position shift
而[H+] 同時有關個個A- equilibrium 事
問題在?

問題在你上面自己計左HA:A- = 50000:1
亦即係話個eqm本身係極度LHS
所以題目話慢慢加NaOH入去時 係應該會睇唔到轉色
除非你加超多OH 多到push個reaction 個[A-]大返先會睇到黃
