# Who proposed pH scale in 1909?

Søren Sørensen

## What is Sorensen scale?

Sørensen’s scale assigns a pH of 1 to 14, with 1 being the most acidic, 14 being the most basic, and 7 being neutral (neither acidic or basic). The pH scale works in powers of ten, so each jump in number is a multiple of 10 in concentration. For example, a pH of 1 is 10 times more acidic than a pH of 2.

When was Sorensen born?

Jan

How did Soren Sorensen create the pH scale?

Nearly 110 years ago, while running experiments with beer at the world-renowned Carlsberg research lab in Copenhagen, Danish chemist Søren Peter Lauritz Sørensen developed the simple yet enduring pH scale, which measures whether a substance is acidic or basic.

### What is pH in acid rain?

Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.

### What does the pH scale?

pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

What has a pH level of 0?

When a base, or alkali, is dissolved in water, the pH will be greater than 7. A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm−3 has a pH of 0. A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm−3, has a pH of 14.

Is a urine pH of 5 bad?

According to the American Association for Clinical Chemistry, the average value for urine pH is 6.0, but it can range from 4.5 to 8.0. Urine under 5.0 is acidic, and urine higher than 8.0 is alkaline, or basic.

#### What does a urine pH of 6.0 mean?

A neutral pH is 7.0. The higher the number, the more basic (alkaline) it is. The lower the number, the more acidic your urine is. The average urine sample tests at about 6.0. If your urine sample is lower, this could indicate an environment conducive to kidney stones.

#### How can I make my urine less acidic?

To help make your urine more acid you should avoid most fruits (especially citrus fruits and juices), milk and other dairy products, and other foods which make the urine more alkaline. Eating more protein and foods such as cranberries (especially cranberry juice with vitamin C added), plums, or prunes may also help.

What does a pH of 5 in urine mean?

Urine pH typically is 5 as a result of daily net acid excretion. An alkaline pH often is noted after meals, when an “alkaline tide” to balance gastric acid excretion increases urine pH. A high urine pH also is seen in patients who are on a vegetarian diet.

Why is urine pH high?

Abnormal: Some foods (such as citrus fruit and dairy products) and medicines (such as antacids) can affect urine pH. A high (alkaline) pH can be caused by severe vomiting, a kidney disease, some urinary tract infections, and asthma.

## Is a pH of 8 good?

Some people say that drinking slightly alkaline water — with a pH between 8 and 9 — can improve your health. They say it may make you age more slowly, maintain a healthy pH in your body, and block chronic disease like cancer.

## Does vitamin C lower urine pH?

Ascorbic acid (AA) has been studied in the literature regarding to its effects at lowering urinary pH in patients with recurrent urinary tract infections. Results have been controversial. While some studies refuted its acidifying effects, others showed significant reductions in urinary pH after AA supplementation.

What happens when your body is too alkaline?

An increase in alkaline causes pH levels to rise. When the levels of acid in your blood are too high, it’s called acidosis. When your blood is too alkaline, it is called alkalosis. Respiratory acidosis and alkalosis are due to a problem with the lungs.

How do I know if my body is too acidic?

For best test accuracy, the test should be performed first thing in the morning. Urine tests measure the level of acid in the body. Optimal pH levels are between 6.5 and 7.5. When the pH level is lower than 6.5, the body is considered acidic and when the pH level is higher than 7.5, the body is considered alkaline.

### Does baking soda Alkalize your body?

Baking soda (sodium bicarbonate) is a natural substance with a variety of uses. It has an alkalizing effect, which means it reduces acidity.

### Is it safe to drink baking soda daily?

Drinking small amounts of baking soda is not usually dangerous. In adults, this can provide short-term relief from indigestion. However, drinking large amounts of baking soda is dangerous, and it is not suitable for long-term use, use during pregnancy, or use in children.

Can baking soda reverse kidney failure?

“A daily dose of baking soda could help patients with chronic kidney disease avoid having to undergo dialysis,” reported The Times . It said that research has found that sodium bicarbonate can dramatically slow the progress of the condition.

Can a damaged kidney repair itself?

It was thought that kidney cells didn’t reproduce much once the organ was fully formed, but new research shows that the kidneys are regenerating and repairing themselves throughout life.

#### Is coffee bad for kidneys?

Caffeine found in coffee, tea, soda, and foods can also place a strain on your kidneys. Caffeine is a stimulant, which can cause increased blood flow, blood pressure and stress on the kidneys. Excessive caffeine intake has also been linked to kidney stones.
