pH=6,4
The pH of tomato ketchup is 3.85
We can use a pH paper.
The optimum pH of lactase is pH = 6.5.
The higher the pH, the more basic, so a pH of 8 is more basic than a pH of 6.
Thiotrine can be purchased at almost any pool store. Thiotrine is manufactured by Advantis Technologies and is labeled under their Applied Biochemists line of pool products. Any retailer can order this through their local distributor.
The product is called Thiotrine chlorine neutralizer, Bromine is a chlorine that has inert ingredients.No - bromine is not chlorine, although their actions as disinfectants are similar. They are two different chemical elements.Don't forget too that pool chemicals tend to be described very loosely by the primary element in their active compounds, not by the compound names.I had to look up Thiotrine, but find it contains neither bromine nor chlorine compounds because it is designed to neutralise both. It is Sodium Thiosulphate: Na2S2O3 (I can't type the correct subscripts here), i.e. a compound of Sodium, Sulphur and Oxygen, respectively.
PH 75 is the most acid.
pH=6,4
pH 9 - pH 4 = pH 5 It is stronger by 5 pH.
neither pH
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
The pH is determined with a pH-meter.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
Most probably PH 12, that is if you add 8+4
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
