One common way to measure Na concentration in human sweat is through a sweat test, where a sample of sweat is collected and analyzed for its sodium content using specialized equipment. This test is often used to diagnose conditions such as cystic fibrosis where sweat sodium levels are abnormally high.

What creates a Na concentration gradient in the proximal tubule?
The Na concentration gradient in the proximal tubule is created by Na+/K+-ATPase pumps on the basolateral membrane actively pumping Na+ out of the cell, generating a low intracellular Na+ concentration. This drives passive reabsorption of Na+ from the lumen of the tubule into the cell down its electrochemical gradient.
There is a greater concentration of na plus and there is a greater concentration of k plus in the cell?
This describes the ionic distribution across the cell membrane, where sodium (Na+) concentration is higher outside the cell and potassium (K+) concentration is higher inside the cell. This gradient is maintained by the sodium-potassium pump, a vital mechanism for cell function including nerve impulse transmission.
What is the standard concentration of Na OH?
The standard concentration of NaOH is typically 1.0 M for laboratory use.
What best describes the Na plus and K plus concentrations across a neuron's plasma membrane?
Na+ concentration is higher outside the neuron than inside, while K+ concentration is higher inside the neuron than outside. This concentration gradient is maintained by the Na+/K+ pump, which actively transports Na+ out of the cell and K+ into the cell, contributing to the resting membrane potential of the neuron.
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.

In a 200-ml sample of 0.030 M Na3P04 what is the concentration of Na plus?
The concentration of Na+ in Na3PO4 is 0.090 M. This is because for every 1 mole of Na3PO4, there are 3 moles of Na+ ions. So in a 0.030 M solution of Na3PO4, the concentration of Na+ is 3 times that, which is 0.090 M.
What sort of ion distributions are established and maintained by Na -K pump activity?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm

When Na OH is added to water the hydrogen concentration increases what can you conclude about Na OH?
When NaOH is added to water, it dissociates into Na+ and OH- ions. The increase in hydrogen concentration is due to the OH- ions reacting with water to form more H2O molecules, shifting the equilibrium towards formation of additional H+ ions. This suggests that NaOH is a strong base that can increase the hydrogen ion concentration in a solution.
Which electrolyte has the highest concentration in the intracellular fluid?
The electrolyte with the highest intracellular concentration would probably be considered to be sodium chloride (NaCl), or at least Na^+ cation.
