Valid, reliable, also practical in learning the chemistry of electrolyte and non-electrolyte solution materials. The research subjects consisted of validators in their fields, subject teachers, and class XI students of SMA Negeri 13 Padang. This development research uses the Borg & Gall development model. The instrument in conducting this study used validation sheets and practicality questionnaires. The average result from the expert validation questionnaire was obtained at 0.91, meaning the product is valid and can be used. Analysis of question items received an average validity and reliability of questions of 0.50 and 0.88, respectively, indicating that the product is valid and reliable. The difficulty level is 20 "moderate" and 5 "easy" questions, the average differentiating power is 0.42 with good categories, and all deception works well. Based on the results of the practicality questionnaire, an average field trial of 89% of student responses and 91% of teacher responses was obtained, which means that the e-assessment tool uses Kahoot! Easy to use by teachers and learners. Keywords: E-Assessment; Kahoot; Electrolyte and Non-electrolyte Solutions 1. Introduction  According to the Minister of Education and Culture number 23 of 2016 concerning educational assessment standards, assessment is a process of collecting and processing information to measure the achievement of student learning outcomes. In general, the assessment process is carried out through a paper-based test. This assessment process has weaknesses in terms of the cost of paper pawning, the duration of correction time, errors in a correction, and even often causes fraudulent actions and nervousness in students (Hamid, 2016).  Corresponding author.
