Use of concentrated naoh (lye or caustic soda) in soap preparations can produce a very basic product. a good soap tests between ph 7 and 9; ph 10 is rather harsh; a ph of 11 means something is wrong. how does your soap compare with these values? how could you reduce the ph of your preparation?

1. table 2.1 contains information on three techniques for producing $15 worth of bar soap. assume that we said “$15 worth of bar soap cost $3 per bar and all three techniques produce 5 bars of soap ($15 – $3 per bar x 5 bars). so you know each technique produces 5 bars of soap. a) what technique will you want to use if the price of a bar of soap falls to $2.75? b) what if the bar of soap rises to $4? c) what if the bar of soap rises to $5? d) how many bars of soap will you want to produce if the price of a bar of soap falls to $2? e) suppose that the price of soap is again $3 per bar but that the prices of all four resources are now $1 per unit. which is now the least-profitable technique? f) if the resource price return to their original levels (the ones shown in the table) but a new technique is invented that can produce 3 bars of soap using 1 unit of each of the four resources, will firms prefer the new technique?

An elementary student decides to conduct an experiment comparing the effectiveness of two commercial soaps as cleaning agents ("soap 1 and soap 2"), using each in paired tests of different types of stains and colors of cloth, where the only variable is the soap used. the student will use the judgment of classmates to decide if the stains remain equal or if soap 1 cleans better than soap 2. however, the elementary student made no prediction of which soap is expected to perform best.

Will mark brainliest. the truth about antibacterial soap according to discovery fit & health, about 75 percent of liquid soaps claim to be antibacterial. while this kind of soap sounds like a good idea, it is really not more effective than regular soap. soap in general works by binding with dirt and grime and bacteria. this binding action allows the particles to be washed away easily. antibacterial soap really does no more than regular soap. in fact, to be more effective than regular soap, antibacterial soap should stay on your skin for about two minutes to do what it claims it can do. most people do not wash their hands that long. in addition, antibacterial soap may do harm. first it kills both beneficial and harmful bacteria. second, scientists believe bacteria may become resistant to antibacterial agents over time, especially if they are not used correctly. finally, antibacterial soap does nothing to viruses. most of the time, we get sick from viruses, not bacteria. in sum, antibacterial soap does not live up to the hype. you are better off just using regular soap. works cited is antibacterial soap any better than regular soap? it becomes resistant to its own agents. it costs more than regular soap. it is ineffective against dirt and grime. it kills both good and bad bacteria.
