a good raising agent for cakes or any baking for that matter would be sodium hydrogen carbonate, this contains alkaline, the alkaline when heated gives off carbon dioxide, which forms little bubbles all over , in and around the cake making these bigger -being filled with the CO2 makes the cake rise, you can see this when you cut a cake open , the little air pockets/holes all inside the cake.
to thicken the mixture and to help it rise
Allows baked goods (quick bread, cake, cookies, muffins, etc) to rise. Otherwise your end product will most likely resemble dry cow patties.
To increase the volume of the cake
Baking soda, baking powder or yeast.
It helps it to rise.
Function of raising agents in a muffin?
suiiiii
Carbon dioxide is produced by the raising agents in cakes.
Butter cakes rely on leavening agents such as baking powder, baking soda, or yeast
Baking powder is a raising agent commonly used in cakes, biscuits, etc. If a recipes calls for baking powder, you should use it as it performs the important function of producing gases during the baking process which creates lift and aeration. If you do not use baking powder, where indicated, you will find that your cake will not rise or your biscuits will be flat and lifeless! There are, of course, lots of recipes which do not need baking powder. Also, self raising flour already contains a set quantity of raising agents and therefore recipes which use this as an infgredient are less likely to need further raising agents such as baking powder or sodium bicarbonate.

A raising agent is a liquid or powder that helps things such as: bread, cakes and scones rise. Things like bread rely on raising agents to ensure they have the right texture and form. The raising agent gives off carbon dioxide when it is heated up this forces the mixture to rise. Acidic salts also have this effect when added into a mixture such as bread. However they cause the mixture to rise at temperatures as low as 15 degrees Celsius.
Shortcrust pastry is classically made without raising agents - just plain flour, butter, salt and water.
