Ka values of citric acid
WebValues of Ka can be used to estimate the relative strengths of acids. The larger the value of Ka , the stronger the acid. By definition, a compound is classified as a strong acid when Ka is larger than 1. Weak acids have values of Ka that are smaller than 1. http://clas.sa.ucsb.edu/staff/Resource%20Folder/Chem109ABC/Acid,%20Base%20Strength/Table%20of%20Acids%20w%20Kas%20and%20pKas.pdf
