Very detailed video. As a engineer that works at a large data center that uses evaporative cooling for our plant, we have to generate a lot of soft water every day. Sometimes the conductivity of the water gets a little low and I have to check the water hardness up to 3 times per shift. Thankfully we use simple TDH testing chemicals and also use a Hach DR 890 for more accurate readings. Thank you for the video :)

If I am titrating to find the effect of (temporary) water hardness due to temperature, is it alright if I use this method for total water hardness and then determine the effect of temperature on the change in water hardness (which would indicate the change in temporary water hardness)? How long would I have to let each water sample be at each temperature, before removing from the heat? Lastly, once it cools down and I carry out the titration, should I rinse the water pipette after every trial OR after every interval of water OR not at all? Would greatly appreciate your help and thanks a lot for the video demonstration!

@bppchemistry6682

You can use whichever you wish, or whichever you are asked for. However, due to the fact that water hardness is made up of the combined effect of many different calcium and magnesium compounds, the measurement for water hardness is standardised in terms of Calcium Carbonate - this means that, globally, everyone uses the same units in terms of the same compound in order to avoid confusion and ensure comparability.

What would you do suppose you have a water sample that you want to test for hardness and you find it is too hard that Even after adding all the EDTA the end point is not reached? Help please
@bppchemistry6682
2 жыл бұрын
Make a new, more concentrated EDTA solution and use it to titrate against the water sample. Trial and error will be involved to find the right concentration which will result in a suitable end point. Alternatively, dilute your water sample with distilled water - e.g. if you dilute a 10ml sample to 20ml with distilled water, you will need to multiply your total hardness found by 2 to account for the dilution.

To measure 100 ml of a water sample you used 25 ml pipette 4 times, but would it be better to use a 100 ml measuring cylinder? I thought this would minimize the bias, but at the end I'm not sure

i believe a pipette is still more accurate than a measuring cylinder even when used 4 times. It might be because of its smaller diameter

2 жыл бұрын
To make up 1 litre of a 0.01M solution of EDTA (assuming it's the tetrasodium EDTA) you weigh out 3.8 g of the EDTA solid and make up to 1 litre using deionised/distilled water. (Molar mass of tetrasodium EDTA is 380 g/mol, and 0.01 x 380 = 3.8 g)

Thank you! I am doing this experiment myself and since you used 100 mLs of bottled water and 1 mL of the pH 10 buffer, if I use 50 mLs of water (tap water) instead, must I halve the buffer amount to 0.5 mL too or does it not matter? Also, should I measure the amount of indicator I tap into the water or does that amount not matter either?
@bppchemistry6682
2 жыл бұрын
@@kaylituh For the buffer, yes I would half the amount and use 0.5 mL. For the indicator you are trying to tap in the absolute minimum amount possible, swirl then let sit for a minute to allow the colour to develop. If the colour is too pale to clearly see, add more indicator (again, the absolute minimum amount possible). By using the smallest amount possible, you are already being consistent in your use of the indicator, so I wouldn't worry about weighing it. it is VERY easy to add too much indicator in this titration.

@@lillian9448 To calculate Ca2+ on its own (e.g. for milk) we must remove the Mg first. We do this by adding some NaOH solution to our milk. We leave this for 5 minutes while gently swirling and the Mg2+ will precipitate out as Mg(OH)2 and settle to the bottom. We can then add the indicator and titrate as normal. This will give our Ca2+ concentration. We can subtract this concentration from the concentration we find when doing this titration normally (Ca2+ and Mg2+ combined) to find the Mg2+ concentration.

Yeah, I had the same thought myself when I looked back at the footage for the first time. I had 2.85 x 10^-2 and needed to multiply by 1000. I guess my thinking might have been that I'd rather make sure I wasn't off by an order of magnitude than have to redo the video. What I found more strange was that I used 10^-2 rather than just write out the full decimal value - I'd never normally use 10^-2... Guess having a camera in my face makes me do weird stuff 🤷♂️
