Is Lamb's Lettuce Acidic or Alkaline?
Lamb's lettuce (fresh) is strongly alkaline: Negative PRAL: alkalizing after digestion.
Classification
Lamb's lettuce comes in at −8.3, so it's clearly alkaline: little protein, hardly any phosphorus, but lots of potassium in the small leaves. For a leafy salad, that's a strong value, well above iceberg lettuce. In practice, the dressing and toppings matter most, because bacon, egg and croutons quickly add more acid than the salad provides in base.
In the Vegetables & Salad category, lamb's lettuce (fresh) ranks #11 of 110, sorted from alkaline to acid-forming. More alkaline options include Potato, with skin (−8.7), Chicory (−9.3), Dandelion greens (−9.7). More acid-forming are Celeriac (−8.3), Swiss chard (−7.8), Horseradish (−7.6).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is lamb's lettuce acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Lamb's lettuce (fresh) has a PRAL of −8.3 per 100 g, so it counts as strongly alkaline in your daily acid-base balance.
How much lamb's lettuce do I need for a noticeable effect?
A serving (150 g) of lamb's lettuce adds −12.5 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of lamb's lettuce roughly offsets one of them.
Why is lamb's lettuce alkaline even though it is not a typical alkaline food?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Lamb's lettuce provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−8.3).
