Can baking soda solution conduct electricity?

Adding an ionic solid, or salt, to distilled water produces a solution that conducts electricity. On the other hand, weak electrolytes, such as weak acids and weak bases, produce relatively few ions when dissolved in water. Citric acid and acetic acid (in vinegar) are weak acids. Baking soda and ammonia are weak bases.

In respect to this, why do some solutions conduct an electric current while others do not?

Some are mode of uncharged particles called molecules. Sugar is such a substance. When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity.

Why does pure water does not conduct electricity?

Due to this pure water does not conduct electricity. A solution conducts current when positive and negative ions are randomly dissolved in it. Pure water doesn't have enough ions but when you add HCl you add a strong electrolyte so, after the addition, solution can conduct electricity very well.

Why does salt water conduct electricity but sugar water does not?

When an acid, a base, or a salt is dissolved in water, the molecules break into electrically charged particles called ions. Solutions with ions conduct electricity. Because pure water has few ions, it is a poor conductor. Uncharged molecules that dissolve in water, like sugar, do not conduct electricity.
