Question

pH of a 5 × 10–6M Ba(OH)2 solution is

Answer 1

Hello dear,

● Answer -
pH = 5.301

● Explanation -
# Given -
Concentration = 5×10^-6 molar

# Solution -
pH is nothing but negative base 10 logarithm of hydrogen ion concentration in a solution.

pH of the solution is calculated by formula.
pH = -log(concentration)
pH = -log(5×10^-6)
pH = 5.301

Hence, pH of given Ba(OH)2 soln is 5.301.

Hope this helped...

Answer 2

Answer:9

Explanation:on-site of the solution is = 2× 5×10^-6 =10^1×10^-6

=10^-5

Poh=-log[oh-]

Poh=- log[10^-5]

So,poh=5×log10 [log10=1]

》poh=5 ---------> [1]

Ph+poh=14

From [1]

Ph+5=14

Ph=14-5=9

So,ph=9
