As the concentration of the salt solution increases, the change in mass of the cucumber slice decreases. The cucumber slice gained mass and swelled where mass change is positive, but lost mass and shrunk where mass change is negative.

What happens when salt is added to cucumber?
Osmosis: Adding salt to sliced cucumbers draws out the extra moisture in the vegetable, through a process called osmosis. Over time, the salt absorbs the water from the cucumber. What you’re left with is a slightly drier cucumber, which won’t ruin your salad.
What happens to a cucumber placed in salt or sugar water?
To compensate this imbalance, the water inside the cucumber cells starts moving through the cell membranes into the high concentrations of salt or sugar water on top; this process is called osmosis.
Is salt on cucumbers good?
Salting the cucumbers makes the dressing tasty, not watered down. It also makes the cucumbers taste more like cucumbers. It intensifies their flavor. The salting process takes about 30 minutes and is well worth it.
When salt is added to cucumber slices in a bowl water is observed in the container?
This is because 96% of a cucumber is actually water. When putting the salt, sugar or baking powder on top of the cucumber slice, you should have noticed that over time they became wet and soaked up the water from the cucumber.
Why does a cucumber placed in a concentrated salt solution shrivels?
When a cucumber is placed in a concentrated solution of salt, it shrivels. This is because it loses water in a high concentration medium. The water from the cucumber move out through its semi-permeable membrane. This process is known as osmosis.
What happens to cucumbers after they are placed into a concentrated salt solution for several weeks as they are when canned?
The water in the cucumber cells tries to equalise these different concentrations by moving from the cells to the saltwater solution. As a result, the cucumber loses water and becomes a bit squishy. This environment is referred to as hypertonic.
Why does salt attract moisture?
The positively-charged side of the water molecules are attracted to the negatively-charged chloride ions and the negatively-charged side of the water molecules are attracted to the positively-charged sodium ions. Essentially, a tug-of-war ensues with the water molecules winning the match.
Which process causes the hardening of the cucumber slices?
Cucumber slices are immersed in 0.1% sucrose solution. After 3 hours, the slices are found to be turgid and hard. Which of the following statements explains this phenomenon? The correct answer is “The high concentration of the cell sap in the vacuole causes water to diffuse in”.
Why do you soak cucumbers in salt water before pickling?
You will need a recipe, most of which will tell you to salt your sliced cucumbers and let them sit for about 3 hours (more is better). This salt treatment draws water out of the cucumbers and flavors them, so it’s critically important.
How much salt is in cucumber?
2 milligrams
Sodium is also an electrolyte and works in conjunction with potassium, but cucumbers contain very little of this mineral. For example, a small, 100-gram unpeeled cucumber contains only 2 milligrams of sodium, but almost 150 milligrams of potassium.
Is salt and pepper good on cucumbers?
And the taste is sincerely spectacular. A classic pickling cucumber size, Salt & Pepper is our favorite cucumber for fresh eating, without question.
How long can you soak cucumbers in salt water?
Place the sliced cucumbers and onions into heavily salted water. Let the cucumbers and onions sit in the saltwater brine for at least 1 hour or up to 4 hours. It is safe to leave them right on the countertop while they brine unless your house is on the warm side, then I would suggest placing them into the refrigerator.
What is the effect of salt on the mass of cucumber independent variable?
We hypothesized that if there is a higher concentration of salt solution inside the cell, then the mass of the cucumber will decrease because the salt concentration in the surrounding environment is greater than the salt concentration within the cell, causing water to flow out of the cell via osmosis.
Does salt remove moisture?
Answer: Technically, salt draws out moisture through the process of osmosis. This is the basis for all the theories about drying and toughening properties of salt when in contact with foods.
What happens when you put cucumber in water?
Cucumbers are high in antioxidants and other nutrients. By adding them to water, they make a glass of water more nutritious and antioxidant-rich. Cucumbers are rich in the following antioxidants : calcium.
How do you salt cucumbers?
Happily, salting cucumbers requires only 20 minutes or so and virtually no effort: You just put them in a colander or strainer, toss them with a big pinch of salt or two (the exact quantity doesn’t matter, since most of the salt will flow away with the liquid), and let osmosis do its thing.
How can a salt act as a desiccant?
Its strong affinity with water makes this compound an excellent desiccant, or a substance which absorbs moisture and can maintain dryness. Sodium chloride can easily absorb moisture due to its ionic bonds, which attract the polar molecules of water.
What shrivels salt?
A cell place in salty solution would loose water as water will move from cell to surrounding hypertonic medium by the process of osmosis causing the cell to shrivel up.
How does adding salt in pickles help in its preservation?
Salt gives the good guys an edge.
Adding salt to your pickling brine is one important way to help lactic acid bacteria win the microbial race. At a certain salt concentration, lactic acid bacteria grow more quickly than other microbes, and have a competitive advantage.
What would happen if you placed a slice of cucumber in distilled water?
The increase in water increases its weight. The cucumber slices that were submerged in saltwater shrunk. While the cucumber slices that were submerged in distilled water swelled.
