I have water that is at a pH of 8.0. I want to acidify the water to a pH of 4.0 (for the purpose of watering acid-loving seedlings).
I have two products that I can use to acidify the water:
- Lemon Juice:
$12.47 * 13% tax = $14.09per container
- The volume of the container is 3.8 L
- It takes 15 ml to acidify 1 L of water to 4.0 pH
- Citric Acid:
$22.99 * 13% tax = $25.98per bag
- The weight of the bag is 2.27 kg. Note: according to my measurements, the dry granules equal a volume of 2.3 L (I did not add water to form a solution for this measurement).
- It takes 1.25 ml of dry granules to acidify 1 L of water to 4.0 pH
Which product is more cost effective at acidifying water?
