Ph of solutions
WebThe pH of a solution varies from 0 to 14. Solutions having a value of pH ranging from 0 to 7 on the pH scale are termed as acidic and the value of pH ranging from 7 to 14 on pH … WebEach buffer has a characteristic pH. This can be explained by the Henderson Hasselbach equation! if [A-] = [HA] then... pH=pKa + log [A-]/ [HA] pH=pKa + log (1) pH=pKa + 0 pH=pKa *not*pH = 7 So buffers don't try to maintain neutrality, they try to …

WebFeb 1, 2024 · Acid + Basic = Salt + Water. PH: It is a measure of how acidic or basic a compound is and the PH range generally is 0 to 14. PH value of 7 indicates it is a neutral solution and below 7 indicates it as an acidic solution and above 7 indicates it as a basic solution, and PH range is different for different indicators. WebEven though pH is a unitless value but it is not a random scale. The value is due to the activity of H+ ion in the solution. pH is described as “the negative of the logarithm of the molar hydronium-ion concentration.”. pH Formula is expressed as. p H = − l o g [ H 3 0 +] The pH Formula can also be expressed as. p H = − l o g [ H +]
