- H₂SO₄
- H₃PO₃
- HCl
📝 Batafsil tushuntirish
1 g kislota neytrallashi mumkin bo'lgan NaOH massasini hisoblash:HCl: n = 1/36,5 = 0,0274 mol → NaOH: 0,0274 × 40 = 1,096 g
H₂SO₄: n = 1/98 = 0,0102 mol → NaOH: 0,0204 × 40 = 0,816 g
H₃PO₃: n = 1/82 = 0,0122 mol → NaOH: 0,0244 × 40 = 0,976 g (2 valentli kislota)
H₄P₂O₇: n = 1/178 = 0,00562 mol → NaOH: 0,0225 × 40 = 0,899 g
HCl eng ko'p NaOH ni neytrallaydi (1,096 g).
