He aha te Bromocresol Green With CAS 76-60-8?

Ko te Bromocresol kakariki he paku memeha ki te wai me te wairewa ki te waiwaro, ether, ethyl acetate, me te benzene. He tino tairongo ki te kawakore, ka huri te matomato o Bromocresol ki te tae kikorangi-matomato motuhake ina tutaki ana ki nga wairewa wai kawakore. Ka taea te whakamahi i te Bromocresol green hei tohu, he kowhai i te pH 3.8 me te puru-matomato i te pH 5.4.
