This app is simple simulation how to determine pH value of the solution, based on changing the pH paper color. Basically pH paper dipped into the solution, the paper will be changing the color appropriate the pH value itselft. Please try to guess the pH value at every solution by matching the changing color with the reference pH color beside it.
这个程序是简单的模拟如何确定解决方案的pH值,根据不断变化的pH试纸的颜色。基本上pH试纸浸到溶液中,纸张会改变颜色适当的pH值itselft。请尝试通过与基准pH值的颜色它旁边的改变颜色匹配每一个解决方案来猜测的pH值。
