Если добавить перекись водорода в подкисленный раствор марганцовки, то объём выделяющегося в результате реакции кислорода начинает намекать, что процесс фотосинтеза может быть и переоценен. Тем не менее не рекомендую от него отказываться, если у вас ограниченные количества реактивов, необходимых для этой реакции:
5H₂O₂ + 2KMnO₄ + 3H₂SO₄ → 5O₂ + 2MnSO₄ + K₂SO₄ + 8H₂O.

А изменение цвета связано с тем, что фиолетовый цвет раствора с ионами MnO₄⁻ постепенно обесцвечивается, так как марганец в результате реакции переходит в бесцветную степень окисления Mn²⁺.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
