Re: Boric Acid

I remember I bought boric acid from Alysson's. this is the chemical store near the corner of San francisco del monte and Araneta ave. I use boric acid as one of the micronutrients or elements for hydrophonics. Used to plant lettuce using soilless medium and nourished by hydrophonic solution.

I still use it for my orchid farm. I blend my own foliar fertilizer

Re: Boric Acid

This should be in the Chemistry Section for future reference. But anyway:

The formula for concentration is:

C = n / v

C = concentration in mol L^-1
n = amount in mol
v = volume in L

We also know that:

n = m / M

n = amount in mol
m = mass of sample in grams
M = molar mass of sample in grams

Substituing n = m / M into C = n / v yields:
