What is the pH of a solution with a concentration of hydronium ions of 8.42 × 10–5?
Nice to see you again @heyo
pH = -log(H3O^+) = -log(8.52E-5) = 4.+, my guess is about 4.1 but I don't have the log tables memorized. :0)

Lol hi! Btw you probably don’t remember this but I’m srry for being rude (this was weeks ago)
i remember it, i just kinda let it go
To determine the pH of a solution, you need to know the concentration of hydronium ions (H3O+). pH is a measure of the acidity or alkalinity of a solution and is defined as the negative logarithm (base 10) of the hydronium ion concentration.
In this case, the concentration of hydronium ions is given as 8.42 × 10–5. To find the pH, follow these steps:
1. Take the negative logarithm (base 10) of the hydronium ion concentration:
pH = -log[H3O+]
2. Substitute the given concentration into the equation:
pH = -log(8.42 × 10–5)
3. Calculate the logarithm using a scientific calculator or math software:
pH ≈ 4.07
So, the pH of the solution with a concentration of hydronium ions of 8.42 × 10–5 is approximately 4.07.
