Does the solubility of potassium nitrate in water increase or decrease as the temperature rises?
Increase
How the hormone epinephrine increases the pumping rate of the sodium-potassium exchange pump in skeletal muscles?
Na would decrease, K would increase
What happens to the hydroxide ion concentration in water when a base is added?
No. A base decreases the amount of hydronium, and increases the amount of hydroxide.
Why does hydroxide act as a base in sodium hydroxide and as an acid in acetic acid?
Hydroxide is a Bronsted-Lowry base, meaning that it accepts protons from other substances. When sodium hydroxide ionizes, it forms the following: NaOH + H2O --> Na+ + OH- In the Arrehnius definiton, it increases the amount of hydroxide. In this case, sodium hydroxide does so. Also, when measuring pH, NaOH gives an alkaline reading, meaning that the pH is above 7. This is due to the decrease of hydronium and the increase of hydroxide. Sodium Hydroxide is not in Acetic Acid. Acetic Acid is CH3COOH (also known as HC2H3O2).
Does the acid increase the concentration of hydrogen ions in the solution?
The pH increases. There are two ways to think about this. First, adding hydroxide ions is the same as adding a base, and a base will cause the pH of a solution to become more basic, i.e. increase. Second, hydroxide ions will react with hydrogen ions in the solution to neutralize them, decreasing the concentration of hydrogen ions. Since the pH scale is a negative logarithmic scale, a decrease in the concentration of hydrogen ions means an increase in pH.
Does the solubility of potassium nitrate in water increase or decrease as the temperature rises?
Increase
Will calcium chloride increase or decrease sodium chloride rejection in a membrane filter?
It will increase rejection of NaCl but will reduce recovery of mambrane. Vivekthakur01@gmail.com
If the mass of sodium chloride dissolves in H2O does the mass increase or decrease?
The mass of sodium chloride remain constant.
Does an increase in ECF K plus level increase heart rate?
Potassium levels DECREASE heart rate, and maybe lead to severe cardiac arrest.and for sure, this is a mechanism of how potassium level in ECF can decrease heart rate:first, the potassium level increase in ECF making its efflux increase, due to activation of potassium channels in pacemaker cells, then the slope of pacemaker action potential will decrease, which means that the duration of one beat is prolonged, and this lead to decrease the numbers of beats in one minute, which by turn means that the heart rate is decreased.
Does an increase or decrease in potassium extracellular ions hyperpolarize a cell?
An extracellular increase of potassium (increase of intracellular Sodium) causes depolarization. The opposite, I presume, meaning high intracellular potassium (inside cell) and high extracellular sodium (outside cell) would be hyperpolarization
If solid sodium hydroxide were added to neutralize the HCl would this reverse the reaction and cause the sodium chloride to redissolve?
No, adding solid sodium hydroxide to neutralize hydrochloric acid (HCl) would not cause sodium chloride to redissolve. The reaction between sodium hydroxide and hydrochloric acid forms water and sodium chloride, which remains in its dissolved form. The addition of solid sodium hydroxide would simply further neutralize the acid and increase the concentration of the resulting sodium chloride solution.
How can a person increase potassium level from 2.8 to 3.5 in one day.?
Then you will be given potassium chloride mix in your IV or eat diet rich in potassium like cantaloupe, bananas, apples and oranges. Potassium level should be around 3.5 to 5.5.
How much potassium is in degrees Celsius?
Somehow your units seem odd.Temperature and quantity of potassium seems strange.Potassium is a metal, somewhat like Sodium. It has a melting point of 63.25°C, and a boiling point of 760°C. Like Sodium, pure Potassium Metal will burn in contact with water.However, it is often found in an ionic compound for example Potassium Chloride (KCl) which is far less reactive.KCl salt is soluble in water, and will decrease the melting point and increase the boiling point of the water.

Na would decrease, K would increase
Why the change in surface tension is much less when sodium chloride is added to water in place of an equivalent amount of ethanol?
Sodium chloride increase the surface tension of water and methanol decrease the surface tension of water.
Does heat increase or decrease thermal energy?
increase
