Answer» alization reaction OCCURS when a strong acid reacts with a strong BASE to produce water and a salt (ionic compound). In our case, sulfuric acid (strong acid) will react with sodium hydroxide (strong base) to form water and sodium sulfate:H 2 S O 4 + 2 N a O H → N a 2 S O 4 + 2 H 2 OWE start with the units that we want to end up with and we set that equal to our given value, which will be MULTIPLIED by a conversion factor (the molar ratio from the balanced chemical equation). The 98.08 G mol represents the molar mass of sulfuric acid and the 40.0 g m o l is the molar mass of sodium hydroxide.So what we have is,g2NaOH=25.0gH2SO4×1molH2SO4/98.08gH2SO4×2molNaOH/1molH2SO4×40.0gNaOH/1molNaOH=20.4gNaOH |
