Is acetic acid more weak than formic acid?
Yes. Formic acid is a strong organic acid, and is also a strong reducing agent.Acetic acid does not dissociate very well, but will do so when forced to in an increasing water concentration, as the equilibrium shifts as more water is available to create hydrogen bonds with the carboxylic group, allowing the hydrogen (or hydronium ion) to solvate
What is the molarity of 37% HCl?
The reagent used in laboratories is HCl dissolved in water, which is why you'll find in the label that it is around 37% HCl in weight. The other 63% is water.
