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. 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. r bread tube
