Ph scale buffers
WebJan 17, 2024 · The pH scale is an inverse logarithm that ranges from 0 to 14: anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is … WebAug 13, 2024 · pH is a logarithmic scale that we use to determine the acidity or the basicity of an aqueous solution whereas, a buffer is an aqueous solution that tends to resist the change in pH. This is the key difference between pH and buffer. Moreover, the pH is a very important scale in chemistry.
