OK

pu2. They sell sodas or baking soda at regular marts. It's easy to get it at big supermarkets like E-Mart

OK

pu3. It's sold at the mart, but when you buy it, check what you buy it for and buy it for. They also sell baking soda for that purpose because they use it for cleaning. If you want to buy baking soda, you can buy it separately
