What dissolves in water better sugar salt baking soda?

All three substances - sugar, salt, and baking soda - dissolve in water. However, their solubility varies.

1. Sugar: Sugar has a high solubility in water. It means a large amount of sugar can dissolve in a given volume of water. Sugar molecules have a strong affinity for water molecules, allowing them to form hydrogen bonds and disperse evenly throughout the water.

2. Salt (Sodium Chloride): Salt also dissolves well in water, although its solubility is slightly lower compared to sugar. Sodium and chloride ions in salt dissociate when they come in contact with water molecules. The positively charged sodium ions are attracted to the negatively charged oxygen atoms of water, while the negatively charged chloride ions are attracted to the positively charged hydrogen atoms of water. This electrostatic attraction enables salt to dissolve in water.

3. Baking Soda (Sodium Bicarbonate): Baking soda has a moderate solubility in water. When baking soda dissolves in water, it undergoes a chemical reaction to form carbonic acid (H2CO3) and sodium ions (Na+). This reaction produces carbon dioxide gas bubbles, giving baking soda its characteristic effervescent property. The solubility of baking soda is lower than that of sugar and salt, but it still dissolves reasonably well in water.

In summary, sugar dissolves the best in water, followed by salt and baking soda.
