Kimia Berapakah pH larutan jika 4 gram NaOH (Mr = 40) dicampurkan dengan 1 L H2SO4 0,01 M?

Berapakah pH larutan jika 4 gram NaOH (Mr = 40) dicampurkan dengan 1 L H2SO4 0,01 M?

Jawaban:

M NaOH . V NaOH = M HCl . V HCl

mol NaOH = M HCl . V HCl

0,4/40 = 0,1 . V HCl

0,01 = 0,1 x V HCl

V HCl = 0,1 L = 100 mL
