the chemist found that 25 cm 3 of 0.2 mol dm-3 potassium hydroxide solution
neutralised 25 cm3 of acidic waste.
What is the concentration of the acidic waste?
Asid sulfurik adalah salah satu bahan kimia penting yang digunakan dalam
perlombongan timah. Ia juga adalah bahan sampingan perlombongan apabila
bercampur dengan air membentuk air kumbahan berasid. Dalam suatu pentitratan,
seorang ahli kimia mendapati 25 cm3 larutan kalium hidroksida 0.2 mol dm-3
