You would wan to dilute the trisodium citrate in distilled water to create a 1% solution. So if you wanted 100mL of solution, you would mix 1mL of trisodium citrate with 99mL of distilled sterile water.
Find the volume of the 100% ethanol Add 1/19 of water to the volume (if it is like 190ml, add 10ml of water since 190/200=95%)
no. but, .1 is the same as 10 percent. .1 "percent" is different than just .1
1 percent of a percent is 1/10000 or 0.0001; this is the same as saying 1 percent percent. Example: 5 percent percent is 0.0005, so 5 percent percent of 100 is 0.0005 x 100 or 0.05.
1/100 as a percent = 1%
NO. 1 percent is less than 5 percent.
To prepare a 1% solution of sodium citrate, you would mix 1 gram of sodium citrate with 99 grams of water (for a total of 100 grams solution). Stir the mixture until the sodium citrate is fully dissolved in the water.
To prepare a 1.25 M solution of sodium citrate, dissolve 294.1 grams of sodium citrate dihydrate powder in 1 liter of water. Mix well until the powder is completely dissolved. Adjust the volume if necessary to reach exactly 1 liter.

For example, if a pH 4.9 buffer is desired, the second pKa should be used and the conjugate acid/base pair for this pKa is dihydrogen citrate and hydrogen citrate. Each of these conjugate acid/base concentrations can be multiplied by the overall volume desired to get the desired volume. However, if not all four compounds are readily available (which is quite common), each one can be generated with acid/base chemistry. For example, if only 1.0 M citric acid is available and 100 ml of 0.2 M pH 7.0 buffer is required, 0.2*0.100/1.0 = 0.02 L or 20 ml of citric acid should be used and (0.15985*3+0.04015*2) *0.100/1.0= 0.055985 L or 55.985 ml of 1.0 NaOH should be added to the citric acid to make the required amount of citrate and hydrogen citrate. This makes up for 75.985 ml and the rest 24.015 ml should be topped up with distilled water.

Sodium citrate is composed of around 13% sodium by weight. This means that 1 gram of sodium citrate contains roughly 130 milligrams of sodium.

Yes, Bacillus amyloliquifaciens typically shows a positive reaction for citrate utilization due to its ability to metabolize citrate as a carbon source. This can be confirmed using citrate utilization tests in a laboratory setting.
Typically, you would use enough water to dissolve the desired amount of ammonium citrate completely. The ratio of water to ammonium citrate can vary based on the specific recipe or application, but a common guideline is to use approximately 1 part ammonium citrate to 3 parts water by weight.
