WebMar 5, 2024 · The pH scale measures whether there is more hydronium or hydroxide in a solution. In other words, it tells us how basic or acidic the solution is. A lower pH means something is more acidic, also known as a stronger acid. A higher pH means it is more alkaline or a stronger base. WebThis is a salt that contains the anion of the weak acid HClO, hypochlorous acid, and the cation of the strong base, NaOH. Because NaOH is a strong base, it fully dissociates into Na+ ions and OH- ions. However, the HClO is weak and does not fully dissociate. Therefore, there is more OH- ions inside the solution and less H+ ions.

As … WebSep 16, 2024 · 14.00 = pH + pOH. The hydronium ion molarity in pure water (or any neutral solution) is 1.0 × 10 − 7 M at 25 °C. The pH and pOH of a neutral solution at this temperature are therefore: pH = − log[H3O +] = − log(1.0 × 10 − 7) = 7.00. pOH = − log[OH −] = − log(1.0 × 10 − 7) = 7.00. And so, at this temperature, acidic solutions ...

WebYeah, exactly. A neutral pH is only true at 25°C because Kw 1.0x10^(-14). If the temperature changes then the Kw also changes which means what constitutes a neutral pH also changes. A neutral pH of 7 is used because 25°C is average room temperature in most places. Hope that helps. WebJan 30, 2024 · The pH of an aqueous solution is based on the pH scale which typically ranges from 0 to 14 in water (although as discussed below this is not an a formal rule). A pH of 7 is considered to be neutral. A pH of less than 7 is considered acidic. A pH of greater than 7 is then considered basic.
