Phloem sap is generally alkaline with pH ranging from 7-3 - 8-5 and contains high levels of-xA0-xA0-K-xA0-and Mg2-xA0-Hence- the chemical test for alkalinity will help to identify that the exudated sap is phloem sap-xA0-So- the correct answer is -apos-Alkaline-apos-xA0-

Phloem sap is generally alkaline with pH ranging from 7.3 - 8.5 and contains high levels of K $^{+}$ and Mg $^{2 +}$ . Hence, the chemical test for alkalinity will help to identify that the exudated sap is phloem sap.
So, the correct answer is 'Alkaline'.
