Hello, I've measured the pH of a med containing sodium citrate, potassium citrate and citric acid, why was is slightly acid if sodium citrate is basic ?
How can I measure the pH of a non acquous solution using litmus paper ?
Does some compund is, for example, basic when solid and became acid when put in water ?
thanks
