I have learn acid and alkaline topic . i think that this topic is fun and intresting . through the experiment i like the most is mixing the acid and alkali and see that become what colour , in acid and alkaline topic i also have learn the natural indicators . i mix the methyl orange with acid , alkali and the neutral substance . for acid it will turn red , alkali will turn yellow and the neutral substance id remain the same. the neutral ph level is 7 , i also learn that acid taste sour while alkali taste bitter .
