pH measurement is an important parameter in nearly every water quality application. In environmental sampling and monitoring, high or low pH values can be indicative of pollution. To determine the pH of water, a pH meter can be used to measure this impor
How do you decide whether a compound is a buffer or not? Would a solution of CaI2 and HI constitute a buffer? Explain. How does a buffer work? What determines the greatest buffer capacity when looking at solutions? How do you know if the buffering capacity of a buffer solution is...
pH stands for potential of hydrogen ie, pH of the solution determines the concentration of protons(Hydrogen ion) in the solution. The strong acids have low pH value(in terms of pH scale) while the weak acid has a high pH value.Answer a...
I have done lots of research on this and used Equation 1 M1V1 = M2V2 I have 5ml of a pH 11.5 cleaning fluid and I am adding 1 litre of water what is my new pH? I do the negative log of pH11.5 to get 3.16 x10^-12 when I plug this into Equation 1 3.16 x10^-12 * (5ml)/...
The most commonly used analysis method in water supplies is measuring specific conductivity, which determines the presence of ions in water. A factor determining the water type converts these measurements to TDS values. Conventional water treatment techniques do not effectively remove TDS. ...

(Hambrick & McCord,2010). Cognitive appraisal determines whether an event is experienced as stressful or not (Lazarus & Folkman,1984). For some employees, idle time may have huge consequences on well-being and job satisfaction while for others this impact might be rather low. Some of the ...

This, together with the fact that the male reproductive organs are located outside the pelvis, determines the factors that can affect the quality of a semen sample. On the one hand, the location of the testicles outside the body means that their temperature is below the temperature of the ...
Inventory is important because it’s often the largest current asset a company has. Your inventory determines how many products a brand can make and sell in a given timeframe and is a prime indicator of what’s hot and what’s not. Managing your inventory should be at the top of your...
