titration係滴定
如果你講acid base 既話 肯定係出neutralization
當然你要知道strong /weak acid/base係咩野
用咩indicator
ce唔會出得好深入
HCL +H2SO4 -->?
應該出呢D 冇記錯的話

strong acid = more ionized in water
weak acid = slightly ionized in water
base = metal oxide , not soluble in water
ph meter , universal indicator
HCL + H2SO4 --> ( 兩隻都係ACID 黎GA 喎- -)
