You did not identify the amount of oxalicacid and so he questions cannot be answered. Work out how many moles of oxalic acid you added to the first 100mL. You then took 10mL, which is 10% of this number of moles into the new container. So you have 10% of the original number of moles in the new 250mL. molarity is mol per litre. so multiply the 10% by 4 to get your molarity. So if you put 8 moles in the 100ml container to start, u then took 0.8 moles to the next container and made it up to 250mL So 0.8 mol per 250mL is equal to 3.2 mol per 1000mL (per litre). Molarity is therefore 3.2

Someone said: I'd advise not even venturing into the land of 40vol. 40vol is so so so damaging, it took me 5 months to grow out the mess it left my hair in. Try 20-30vols first and if you dont get a good result, use 40vol for about 45 mins AT LEAST 2 weeks after using the other bleaches.

Someone said: Use a 20 and cover your head with a plastic cap

Someone said: then a BLUE OR PURPLE TONER, OR SHAMPOO

Answer is provided by a lic. Cosmetologist of 10 yrs. Ten volume developer is generally used to deposit color. It has very little lift. I would suggest using 20 volume. Also take into consideration what you are trying to lift. You have to pay attention to your base colors within the color you intend to use. Sometimes when lifting a brown you can end up with reddish undertones. If hair is already blonde and you wnto lift to a lighter blonde, depending on your hair`s undertones, you could end up with undesireable results. Undertomes are the colors you see in your hair if you were to step outside in the sunlight and see shimmers of other colors, such as gold, red, and/or copper.

Someone said: Intrigued... The salon I work at uses Paul mitchell and Rusk. Is it acceptable to mix my 40 volume Rusk developer with Paul Mitchell The Color UTP toner?

lmcruz10 said: my hair is auburn but my roots are black from my hair growing. i bought jet black coloring but i have 30 volume creme developer, would this work for darkening my hair?

jennareisling said: I am a salon owner, and we use Paul Mitchell color. Do not use your 40 Volume Rusk with it. Of course, 40 Volume is just that, it is very invasive,and you will get a lifting result, however, results can not be guarenteed. I do color all day long, every day, and I cannot remember the last time I used about a 30 Volume in Paul Mitchell to achieve what I wanted, so I am not a 40 volume supporter unless absolutely necessary, and certainly not out of color line being used. Hope this helps

Someone said: thank you very much! Your answer was just what I needed!!

you should do it again once more time on the ends only with 20 volume, you can try 30 vol, but i dont know how ur hair condition is, if u have go0d hair then go ahead and do it with 30 vol, but if u see ur ends are not not healthy do it with 20 vol. try not to touch ur roots, just apply on the parts where u see is darker.
