请教一个AP chemistry的问题
a solution is prepared by mixing 90.0mL of 0.050 M HCl to 30.0mL of 8.00 M HNO3.water is then added until the final volume is 1.00mL.Calculate [H+] [OH-],and the pH of the solution
答
final volume is 1.00mL?抱歉是1.00Lc(H+)=(0.09*0.05+0.03*8)/1=0.2445mol/Lc(H+)*c(OH-)=1*10^(-14)c(OH-)=4.09*10^(-14)PH=-lg c(H+)=-lg(0.2445)=0.612
