Question

What is ph scale what is ph value of salt formed by a weak acid and strong base?

Answer 1

Hi there,

◇ pH scale : it is a scale used to determine the solution acidity or how the solution basicity

◇ Its range frome 0 : 14 divided into 3 parts

● Acidic from 7 to 0

● Neutral 7

● Basic from 7 to 14

☆ pH of salt solution depend on the strenght of the acid and base forming the salt

◇ If strog acid react with strong base , forming neutral salt pH = 7

◇ If strong acid react with weak base, forming acidic salt , pH <7

◇ If strong base react with weak acid , forming basic salt , pH > 7
