Is the same product for alkalinity increaser and/or ph increaser ?

No. Alkalinity Increaser (which is baking soda or sodium bicarbonate) is not the same as pH Increaser. Those are different products. If you have a good way of aerating your water, i.e., creating lots of bubbles (like in a hot tub), you can actually increase pH through aeration. In a hot tub, it is more likely that you would need pH Decreaser if you use the jets often. I rarely use pH Increaser in my pool. More often than not I need to decrease the pH level. You can use muriatic acid (sold in hardware stores) to accomplish that.

Is the 50 lb bag powder or granular?

I use plain old Arm & Hammer baking soda a powder. That is what will increase Alkalinity.

can this be used with laundry?

Yes, This chemical may be used in laundry, mostly to remove stains: create a paste with small amount of water and scrub on tough stains. It's good on colors, hot or cold water, and as a disinfectant. For tough dirty laundry you may need a soaping detergent as well..... good luck.....
