Scenes which aired earlier this week saw Daisy’s stalker Justin Rutherford (Andrew Still) throw sulphuric acid over Ryan Connor (Ryan Prescott).
However, the scenes divided opinion and Ofcom received 72 complaints about the episode.
In the dramatic plot, Justin had been trying to attack Daisy (Charlotte Jordan). But Ryan heroically jumped in the way and took the brunt of the attack, ending up injured.
Some fans of the ITV soap were unimpressed, with one calling it "totally irresponsible" and tweeting that it was "an epic fail".
Another suggested that it was in bad taste.
However, others praised the soap for tackling a "vitally important" issue.
"Such a horrific but important storyline @itvcorrie," tweeted one.
"So well handled and @ryanaprescott played his part so well. How is acid so readily available to the public? Truly harrowing."
"The acid attack scenes in #coronationstreet tonight will stay with me for a long time," said another fan.
"What a tough episode but so well acted. Had tears watching it and my heart and chest felt like they froze.
"Well done to everyone involved in this story."
"Another said: I'm not prepared #coronationstreet for tonight BUT it's vitally important and a very real storyline of women being attacked mainly by violent, obsessive men with acid. For those saying it's too depressing or dramatic.
This happens! It needs to be spoken of."
