Which of the following solutions will have pH close to 1.0 ?

Options

A. `100mL of M//10 HCl+100mL of M//10NaOH`
B. `55mL of M//10 HCl +45mL of M//10 NaOH`
C. `10mL of M//10 HCl+90mL of M//10 NaOH`
D. `75mL of M//5 HCl+25mL of M//5NaOH`

Explanation

`{:(a,HCl,NaOH),(,"No of milli eq."=(1)/(100)xx10=10,(1)/(10)xx100=10),(,"so solution is Neutral",),(b,(1)/(10)xx55=5.5,(1)/(10)xx45=4.5),(,[H^(+)]=(1)/(100)=10^(-2)M pH=2,),(c,(1)/(10)xx10=1,(1)/(10)xx90=9"Basic"),(d,(1)/(5)xx75=15,(1)/(5)xx25=5),(,[H^(+)]=0.1MpH=1,):}`
