AI Generated Solution

To find the value of \( K_w \) at a certain temperature given the hydronium ion concentration in pure water, we can follow these steps: ### Step 1: Understand the relationship between hydronium ions and hydroxide ions in pure water. In pure water, the concentration of hydronium ions \([H_3O^+]\) is equal to the concentration of hydroxide ions \([OH^-]\). This is due to the nature of water being neutral, which means: \[ [H_3O^+] = [OH^-] \] ...
