A city lawyer argued that the teacher who conducted a chemistry experiment gone awry shouldn’t be blamed for the accident that badly burned a Beacon High School teen — and the former student should be awarded no more than $5 million in damages.

Mark Mixson, who reps the Department of Education and former teacher Anna Poole, made the statements in closing arguments at the trial that pupil Alonzo Yanes, now 21, brought against the city and Poole for the horrific Jan. 2, 2014, incident that left him disfigured for life.

“I cannot have her [Poole] be sacrificed on the altar of this feeling that we have to do justice,” Mixson told jurors as Poole looked on in the Manhattan Supreme Courtroom crying.

“I feel for him [Yanes] every day … don’t do justice over the broken spirit of Miss Poole,” Mixson said concluding his three-hour arguments.

Earlier, Mixson refuted the claims that Poole’s alleged negligence in conducting the “Rainbow Experiment” is what led to the fireball that engulfed Yanes — who was 16 years old at the time — leaving him with third-degree burns over 30% of his body.

Mixson suggested instead the incident was an inexplicable freak accident.

“They want you to tell Anna that she is negligent because she wasn’t taking care of the things the way she should have and that’s not true,” Mixson argued.

“This is a ubiquitous demonstration that has been demonized by the press to make Anna Poole look terrible. They are doing it now,” the lawyer continued.

“Ms. Poole said that she treated these kids like her kids. I want to suggest to you that everybody here should be appreciative of people like Miss Poole,” he said.

“The world we live in, for a lot of people, maybe not you, has no meaning, no justice, no karma, it just is, an existential,” Mixson said trailing off.

Lawyers for Yanes and his parents have argued that Poole poured a gallon jug of highly flammable methanol directly onto a dish that held salt in the demonstration she was conducting to show the different colors that various salts produced.

Poole and Mixson say she would never have done something so reckless and opted instead to use a beaker and pipette to add methanol to the dishes.

Yanes’ lawyers also claim that he and other students — including Julia Saltonstall, whose arm was burned in the accident — were seated too close to the demonstration table and weren’t equipped with goggles, unlike Poole, who wore them.

“I want Mr. Yanes to know that people do love him and he will find love … and I’m proud to have known him,” Mixson said as Yanes’ parents looked on.

“We have to find meaning in the world and the meaning isn’t always whose fault is this and who is going to pay me.”

Mixson told jurors he thought a reasonable amount of damages to award Yanes would be $3 million for his past pain and suffering and another $2 million for his future pain and suffering.

Yanes’ lawyers are expected to deliver closing arguments on Thursday afternoon.
