Brine Definition and 18 Threads

This question involves a bit of background, so please be patient. I understand that the heat absorbed by ice's phase change from solid to liquid is much greater than the amount that results from the difference in temperature of the ice and the ice cream batter. So the primary cooling effect is...

Also does bad bacteria(mold) forms on the weight(i.e use to submerged the cabbage) ,on the portion that is above the brine. I use glass paper weight, as I think they only form on food surface. My thought, sauerkraut is safe, as long it is submerged inside the brine and mold formation is only...

Hello, I am currently looking at a way to calculate brine density using temperature, pressure and salinity. I found the following page which describes the change in fluid density with pressure and temperature : http://www.engineeringtoolbox.com/fluid-density-temperature-pressure-d_309.html...

Hello all, I am currently trying to convert brine salinity values in ppm to the corresponding brine density. My understanding is that I can do that using ppm * SG = mg/L . However I do not know how to get the Specific Gravity (SG) of my brine. The data I try to convert has a minimum value of...

1. The problem Two very large tanks are each partially filled with 2000 gallons of brine. Initially 5000 ounces of salt is dissolved in tank A and 1000 ounces of salt is dissolved in tank B. The system is closed in that the well stirred liquid is only pumped between the two tanks. Four gallons...

What's a suitable Material of construction for equipment handling hot brine (NaCl) solutions? Temperature is max approx. 100 C. I'm conflicted if or not SS316 works? I looked up an old handbook and it reported a corrosion rate of 0.2 mm/year (@80 C) which seems not too bad to me. But I've...

I did an electrolysis with alluminum eletrodes, the electrolyte was NaCl, After completing it the left over was a gresyish precipitate (I assume aluminum hydroxide), I put most of it for evaporating in a cup, the rest evaporated leaving a jell, then later crystals. are the crystals NaCl which is...

A chemical plant with 3 tanks in succession with mizing of reactants and products. Brine tanks = fresh water flows into tank, mixed brine from tank 1 to tank 2, then tank 2 into tank 3, and out of tank 3. Let xi(t) = lbs of salt in tank i at time t for i=1,2,3 Assume each flow rate is in...

As a casual experiment I was seeing whether I could make hydrogen from sodium hydroxide, aluminium and water. Rather than buy sodium hydroxide or go through a load of cleaning products to find it, I thought it would be much more fun to produce it through electrolysis. I set it up, and the...

Hi, i have been trying to electrolyze brine having carbon as anode and cathode as well;; but i don't understand why the solution is turning yellowish. Can anyone explain it ? thanks.

So we're about to get a decent snowstorm and being a lazy bastard + engineer, I'm considering an experiment with a brine solution (the way the DOT does it) to see if I can reduce my shoevling requirement. I have some normal rock-salt and I'm going to mix some with water and spray it on a...

Here is a esoteric problem that is totally unique in nature: Taylor Glacier, in the Dry Valleys of Antarctica, hosts site of a Fe2+ brine solution, expressed as a rusty discharge at the terminus. There is strong diurnal signals in seismic data gathered from an array co-located there, not...

Homework Statement A tank is initially filled with 1000 litres of brine, containing 0.15 kg of salt per litre. Fresh brine containing 0.25 kg of salt per litre runs into the tank at the rate of 4 litres per second, and the mixture (kept uniform by stirring) runs out at the same rate. Show...

I want to measure salt brines. I can measure specific gravity and degrees Fahrenheit. I need a formula into which I can insert the two measured values and resolve to get the degree of saturation of my brine. I can't find a formula, so I'm not sure a formula exists, but I can't understand why...

Homework Statement A tank contains 80 gallons of pure water. A brine solution with 2 lb/gal of salt enters at 2 gal/min, and the well-stirred mixture leaves at the same rate. Find (a) the amount of salt in the tank at any time and (b) the time at which the brine leaving will contain 1 lb/gal...

hello. I'm new member here. i have some question regarding my brine electrolysis experiment. really hope somebody can help me. I'm using saturated brine in the compartment and graphite as electrode at anode and cathode. i can see the reaction at the anode and cathode was very vigorous and many...

there's an example problem in my textbook, but I'm stuck on how to make the first move~ "a tank contains 1000gal of water in which 200lb of salt are dissolved. Fifty gallonw of brine, each containing (1+cost)lb of dissolbed salt, run into the tank per minute. The mixture, kept uniform by...

Electrolysis of Brine... Why does castner-kellner cell produces Na. I was always told that Na formed too stable an ion to be reduced when it is in aqueous solution even when the solution is concentrated. I myself have carried out this experiment by elecrolysing concentrated aq. Sodium...
