I’ve recently tried mixing the used coffee grounds in baking soda, and I’m seeing a very visible chemical reaction. I haven’t tried putting it in the ground yet though.

Sounds like the acidity doesn’t need to be neutralized. It’s recommended here that you compost them or just mix them into the soil. When I worked in coffee shops we would compost them and then someone picked that up. Also says some plants react better to coffee grounds but you shouldn’t have to apply baking soda because “Fresh coffee grounds are acidic. Used coffee grounds are neutral.”
Hmm but there was a visible chemical reaction when I mixed the coffee grounds and the baking soda, and when water was added it bubbled up. But thanks I’ll look up composting coffee grounds
