Sodium Bicarbonate (aka Arm and Hammer baking soda) raises TA a lot, and pH a little. Sodium Carbonate (aka Soda Ash) raises pH a lot, and TA a little.
Either of these may be packaged under the "name" of pH up, or TA up...depending on the manufacturer. You have to look at the actual ingredients of the product, rather than the name of the product.
