Chemistry: Ratios

[Lee Shively]

I mix D76 1:3. That means I mix 8 ounces of D76 stock solution with 24 ounces of water to make up a total of 32 ounces. When I use it 1:1, I mix 16 ounces of D76 stock solution with 16 ounces of water to make up a total of 32 ounces.

I mix LPD 1:4. That means I mix 10 ounces of LPD stock solution with 40 ounces of water to make up a total of 50 ounces.

I mix Dektol 1:2. That means I mix 16 ounces of Dektol stock solution with 32 ounces of water to make up a total of 48 ounces.

I don't know if it's "+" or ":" that's correct or even if my proportions are correct. I only know it works every time, 100% of the time, to my complete satisfaction.

(I also mix 1.5 ounces of 100% agave tequila with 1 ounce of Cointreau and 2 ounces of fresh squeezed lime juice to make a killer margarita. I have no idea how you write that as a ratio. I just know I need one right now!)

I thought this bit was easy until the question was asked - now I'm as confused as everyone else :confused:

Think I'll join you in your recommended soup here

TPPhotog has a great point about consistancy. It's great if YOU know what you mean with whatever sign you use. However, as has been pointed out, the colon is open to interpretation. Maybe I'll be in the minority, but I'm sticking with the "+" sign. With that one there's no doubt. It will always mean x+y=z. But then I've always said "passenger side " or "driver's side". The left or right front of the car isn't accurate enough and depends where you are standing.
