1.	How many grams of NaOH can neutralise 100 ml ofH_2SO_4solution with P^(H)solution with P^(H)value 3.301?
Answer» 2mg 3 mg 4 mg 0.4 mg Solution :` pH = 3.3 rArr [H^(+) ] = 5XX 10 ^(-4) ` ` therefore ` moles of acid ` = 0.1 xx 5 xx 10 ^(-4)= 5 xx 10 ^(-5) ` to NEUTRALIZE , MOLESOF NaOH`= 5 xx 10 ^(-5) ` ` therefore ` weight` = 40 xx 5 xx 10 ^(-5)= 2 xx 10 ^(-3)= 2 mg `
