Can 50g of NaCl dissolve in 100 g of water at 60 C?*

Explanation:

The solubility of sodium chloride at 60 degree in water is 37.04 gm / 100 mL

or 37.04 gm / 100 gm of water

So 50g of NaCl can not be dissolved in 100 g of water.

the answer is c. nacl

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
