chlorophyll content was changed

[Woo, Jong Ho]

Hi! netters
 Can you tell me about this:
When i experimented on pH buffering effects of leaves of Ginkgo biloba on
various pH solution(pH was adjusted with H2SO4(3):HNO3(1) solution)
chlorophyll content increased with treatment time(1 min. - 48 hr.).
My experiment was correct? And i want to know what is the reason of
increasing chlorophyll content.
