Yes. Some examples: bleach which is 5% Sodium Hypochlorite freezes at about 20ºF ( -7ºC ) and bleach which is 10% Sodium Hypochlorite freezes at about 7ºF ( -14ºC ). Generally, the more you dissolve in water, whether to make bleach or anything else, the lower the freezing point.

All liquids freeze. Some at much lower temperatures than others. "Absolute Zero" (or 0 Kelvin) is when there is no atomic movement. Though the number has never been attained on earth, scientists have been able to get within a fraction of a K. Nothing tested at that temperature has remained a liquid.

Yes. Bleach is a 3% to 6.15% solution of Sodium Hypochlorite. The manufacturing process also produces Sodium Chloride (common salt) as a byproduct. Without the salt, the freezing point would be about 31 degrees Farenheit. Depending on how much salt is present, the actual freezing point could be 5 or 10 degrees less than that. Since Sodium Chloride is not considered hazardous, manufacturers are not required to say how much of it is in the bleach.
