65342;▽^). Comments on friends' chemistry blog. Her answers are good and detailed. She included some examples to relate to her answers. Her answers (especially for the first question) was quite lengthy so I think she must have done a lot of research. But I think for question 5, it will be better if she can add in the physical properties. For sulfide ion, there should be a (2-) outside bracket. Chihiro reading comic book. My "Thankyou" letter is pinned on her wall! 1 What does an atom looks like? An atom ...

Thursday, 22 September 2011. Q5 Excess zinc carbonate is added to hydrochloric acid in the preparation of zinc chloride salt. I) Write an ionic equation for the reaction. Ii) Why excess zinc carbonate is used? Zinc carbonate is used to ensure that all the hydrochloric acid is completely reacted.When there is excess zinc carbonate seen,the reaction between the zinc carbonate and hydrochloric acid has stopped. Iii) Briefly explain how the zinc chloride crystals can be obtained. View my complete profile.
