Calculate the pH of a solution that has [H30*] = 5.2 x 10-7M

pH ≈ 6.3

Explanation:

To calculate the pH of an aqueous solution, you need to know the hydronium ion (H₃O+) concentration in moles per liter (molarity).  The pH is then calculated using the expression:

      pH = - log [H₃O+]

Since the solution has an H₃O+ ion concentration of 5.2 × 10⁻⁷ M, we can plug that in and solve:

      pH = - log [5.2 × 10⁻⁷]

      pH = 6.28

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.

im not exactly sure but i think its b!
