Webb16 juni 2016 · 2. In the moment from the video that you referred to, Sal was using the equation p K w = p H + p O H to find the p O H of the solution. p K w is equal to 14, since K w is equal to 1 × 10 − 14, giving us the new equation 14 = p H + p O H. We know that the p H of a 1M solution of H C l is zero from earlier on in the video.

That is, near 25oC, the sum of the pH and pOH is always 14.00. Therefore, pOH = 14.00 − pH = 14.00 − 7.0 = 7.0. Since the pH and pOH are equal, this solution is said to be neutral; i.e. it is neither acidic nor alkaline (basic). Answer link. how many in congress are over 80WebbNotice, since we have two significant figures for the concentration, we need two decimal places for our pOH. So to find the pH, we know that pH plus pOH is equal to 14.00 at 25 degrees Celsius. So we can plug in the pOH of 2.70, and that gives us pH plus 2.70 is equal to 14.00. So the pH of the solution is equal to 11.30. how many incorporated towns in usWebb11 mars 2024 · The concentration of hydroxide ion of a solution whose pOH value is equal to 2.86 is 1.38×10⁻³ M..
