pH=12.6pH=12.6

Explanation:

We know that in aqueous solution under standard conditions.....

pH+pOH=14pH+pOH=14.

And pOH=-log_(10)[HO^-]pOH=log10[HO]; so here pOH=-log_10(0.041)=pOH=log10(0.041)=

-log_(10)0.041=-(-1.39)=1.39log100.041=(1.39)=1.39.

And thus pH=14-pOH=12.6pH=14pOH=12.6

So is this solution acid or alkaline?
