The idea of combining baking soda and also lemon juice color etc on straightforward principles that acidity and the pH scale.

Scientists usage the pH scale to measure up the acidity of a solution. A solution have the right to have a pH level in between 0 and also 14.

The reduced the pH, the much more acidic the solution, so:

pH levels listed below 7 show an acidic solutionpH levels above 7 show an alkaline, or base solutionneutral solutions, such as pure water, have a pH of 7

Baking soda, likewise known as salt bicarbonate, is a base. This means that when human being dissolve baking soda in water, it creates an alkaline solution. Because that example, a 0.1 molar solution of baking soda has actually a pH of about 8.3.

Lemon juice includes citric acid and also has a pH of approximately 3. Including baking soda come lemon juice will certainly raise the pH to produce a more neutral solution.

Skin care

Usually, the skin has actually a weakly acidic pH of about 5.7. Bases, such as baking soda, will rise the pH of the skin. Higher pH levels deserve to disrupt the barrier function of the skin, i m sorry may result in dryness, overabundance oil production, and also acne.

Lemon juice appears to have apparent skincare applications because it contains concentrations that vitamin C and citric acid, i beg your pardon both provide powerful skin benefits. Citric mountain is one alpha-hydroxy mountain (AHA) that manufacturers generally use in chemical peels.

However, skin cells naturally repel water-soluble molecules, such together vitamin C. This method that very small vitamin C will actually pass through the skin.

A 2017 research examined the antacid effects of various foods. The writer of this research created synthetic stomach acid with a pH of 1.2. Although lemon juice by itself had almost no effect, sodium bicarbonate effectively neutralized the synthetic stomach acid.

Many OTC antacids contain salt bicarbonate and citric acid. Lemons and other citrus fruits are rich resources of naturally-occurring citric acid.

When a human mixes lemon juice and baking soda, the citric acid reacts through the sodium bicarbonate to develop a buffer called sodium citrate. A buffer describes a weak acid or base that prevents drastic pH changes. Although lemon juice does no neutralize stomach acid, the may assist stabilize the pH level within the stomach.


Using baking soda and lemon juice to combat excess stomach acid might be a good home remedy, as effective OTC antacids contain comparable ingredients.

However, mixing the correct proportions that baking soda and also lemon juice deserve to be difficult.

It is additionally important to keep in mind that lemon juice includes high concentration of citric acid and also ascorbic acid, or vitamin C. Acidic compounds have the right to erode enamel and lead to tooth decay. However, combining baking soda and also lemon juice should create a an ext pH-neutral solution.


People interested in whitening their teeth should call their dentist. The American dental Association (ADA) have additionally approved several varieties of baking soda toothpaste. To obtain an ADA Seal, manufacturers must provide scientific evidence to prove their product is safe and effective.

Baking soda has sodium bicarbonate, i beg your pardon is an active ingredient in some medications, such as antacids, and can potentially communicate with other medications. Civilization who intend on routinely consuming baking soda for health and wellness purposes have to speak to a medical professional first.

People who have actually kidney an illness or high blood pressure need to avoid sodium bicarbonate due to the fact that it deserve to increase salt levels in the blood.

Side impacts of sodium bicarbonate can include:

nausea and vomitingthirststomach painexcess gasfrequent urinationswelling of the lower limbs

Lemons contain countless essential vitamin and also minerals. Lemon juice additionally contains compounds that have useful antibacterial and antioxidant properties.

However, lemon juice is acidic and using too lot can reason side effects. These can include:
