Which of the following is strongest oxidising agent?
Which of the following is strongest oxidising agent?
The number of hydroxide ions in 1 cm3 solution of pH = 13 is :
The number of hydroxide ions in 1 cm3 solution of pH = 13 is :
pH = 13, pOH = 1
[OH–] = 10–1
no. of moles OH– in 1L = 10–1
No. of moles of OH– in 1 ml = 10–4 No. of [OH–] ions = 6.02 × 1023 × 10–4
⇒ 6.02 × 1019
