pH of Lemon Juice: Is lemon juice acidic or alkaline? 🍋🍋🍋

To determine the pH of lemon juice we'll use pH paper. Before we test the the pH value for our lemon, we'll make sure our pH paper is accurate by testing it with Hydrochloric acid, a neutral buffer solution, and an alkaline solution of Sodium hydroxide.
On the pH scale the HCl is red, the neutral buffer green, and the NaOH is purple. When we test the pH of the lemon juice we get an orange color. This corresponds to a pH of three on our pH scale. So lemon juice has a pH right around three.
When I tested lemon juice with a pH meter I found it to be 2.76 which is similar to our finding with pH paper. This value likely varies depending on the age of the lemon and the characteristics of the particular type of lemon. But these numbers are close to the reported values for lemon juice in the literature.
So in answer to our question, lemon juice has a pH of around three making it acidic.

Lemon Juice does turn into alkaline once when its consumed

[@cillavalene9288]

Seriously ?

[@aaronscz3270]

@@cillavalene9288this comment is mostly true because it can only be alkaline after digestion due to the activation of pepsin which makes the lemon alkaline/neutralized

[@naxshanmira2357]

@@aaronscz3270Does lemone is acidic or alakaline ??

Thank you your videos are so helpful, I have a question what elements or equation would give you the products of ammonium sulfate and tin (ll) carbonate

[@wbreslyn]

Looks like a double replacement reaction so you would must switch the positive ions (the NH4 + and Sn 2+). But make sure you charges balance with the new compounds.

Thank you Dr B

[@wbreslyn]

Most welcome!

Hi Dr. B! I ran across your video while researching some conflicting reports on lemon juice...mainly it is acidic but becomes alkaline in the human body once metabolized. Do you know if this is true? Or is this "internet fiction?" LOL

[@ponchobarr3455]

True becomes alkaline in your body

I have a doubt?
Is lemon good for skin whitening? And intake,outtake lemon juice also gives skin whitening results?

[@Jsnipes98]

Skin whitening?? Useless!😂 Why use nature to dilute what you are? Your Skin is the color it is, for a reason.😂

[@krokodillg4886]

ye i hear some foods are made my humans like yellow lemon(green alkaline) , green apple , beans , rice

[@end__haze]

how acid works? like it desintegrates things bc of high ph? but i wonder how that works chemically:o

[@jerry7980]

I have a question what is the name of the Material and Apparatus used in this video

[@Suzuchikuma]

Mainly acid citric acid, so pH should be close to pKa

[@wbreslyn]

I believe 6-7% of a lemon is citric acid, so quite a bit.

[@akshyashreesharma6091]

I hv a question if lemon has ph 3 i.e highly acidic then why doesn't it burn our tongue when consumed ?

[@cyanide-e2b]

It is 3 so it will take approximately 1 to 2 minutes to burn your tongue....put only lemon drops into your mouth till it is full then wait for 2 minutes the result will appear

[@jojo-es5ov]

Well.. after the lemon juice is digested , it becomes alkalizing to the body.

how do you upload so much

The pandemic has given me a lot of extra time!

Is that litmus paper please??

Lemon acid insects protein or bees or sloths cynobactari a leaf protective lair microscope

[@Lsvdp369]

But after digestion it has a alkaline ash

[@wbreslyn]

Interesting!
