Class 10 Chemistry Viva Questions With Answers

Class 10 chemistry viva voce question and answers are concept focused and not question focused, which improves the conceptual knowledge based on the practicals performed by the students. Students can revise each and every chapter viva voce questions by referring to the question answers provided and obtain a confidence on them.

A general viva voce is based on the practicals. Prepare accordingly from the set of viva voce given after each experiment. Class 10 Chemistry Practicals Viva Voce Question and Answers is to judge whether the student has merely copied the experiments from the book or he/she has actually performed it in the laboratory. Also this helps to remember about the experiments performed in the laboratory. Keep revising.
