One of the characteristics of soap is that chemically it is a sodium salt of higher fatty acid.

I would expect the pH of a solution of soap to be closer to 9, as soap is typically basic in nature due to the presence of alkaline components like sodium hydroxide or potassium hydroxide in its composition. A pH of 4 would be more acidic, which is not characteristic of soap.
"Soap" is not a single thing, there are lots of different kinds of soap. That said, if you told me that a particular soap had a pH of 9 I'd be a lot more inclined to believe you had some idea of what you were talking about than if you said it had a pH of 4.

The test of soaps with FeCl3 (ferric chloride) is used to identify the presence of phenolic compounds in soap. When a soap containing phenols is mixed with FeCl3, a characteristic color change occurs, often resulting in a purple or violet coloration. This indicates the presence of phenolic groups, confirming that the soap may have been derived from natural oils or fats that contain such compounds. If no color change occurs, it suggests the absence of phenolic content in the soap.
Soap is a surfactant, meaning it lowers the surface tension of water and allows it to interact more easily with oils and grease, helping to lift them off surfaces. It consists of molecules with a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail, allowing it to surround and remove dirt and oil from surfaces. Soap is also able to form a lather when agitated with water, which helps in the cleaning process.

There is no chemical reaction. Lathering is just air bubbles getting trapped inside the liquid. Soap has a high surface tension, and so if you introduce air bubbles inside it, they tend to stay for a while (unlike water for instance, where the air bubble won't stay for long and will just rise to the surface and fall out). This is also why you can blow soap bubbles (but not water bubbles).
No, ivory soap is not castile soap. Castile soap is a type of soap made from olive oil, while ivory soap is a brand of soap known for its purity and mildness. Ivory soap is typically made with a blend of synthetic ingredients.
