yeah swim knows that science doesn't fail..
anyway,he did some speculations to know how to do a pH2 solution with 10% HCL
he has red on wiki that hydrochloric acid at concentration 0.01M has pH2 so..here the calc.
yesterday he bought HCL sold as cleaner at a concentration of 5-15% so swim assumed it's about 10%.
1M HCL=36,5 g/L that means that a 0,01M solution of HCL has 0,36g/L
swim's solution is 10% (2,87M)
that means it's 287 times more concentrated that he needs
so 1ml of its solution must diluted to 287 ml to achieve 0.01M or 3,48 ml/L
that's all but many tings will modify its pH as salts in water if you use tap water and the real concentration of startin acid,if it's 12% the pH would drop almost at 1 swim thinks
