What is the ph of a 6.4 x 10^-10 m oh- solution

pH of the solution is 4.81

Explanation:

pH is defined as the negative logarithm of hydrogen or hydronium ion concentration. It is basically the power of hydrogen ions.

Mathematically,

We are given:

To calculate pH, we first calculate pOH of the solution and then subtract it from 14.

Putting the value of hydroxide ion concentration in above equation, we get:

Now, using the below equation:

Hence, pH of the solution is 4.81

u i forgot the answer?

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
